Hah, I didn’t know Kurt was still in the LSx business. I think he was on ls1tech a lot, is he still? I met him when he ran Wheel2Wheel at least once during my visits there (good friend worked there as an engineer for years). That was one hell of a cool shop - always something crazy going on, whether it was the Garrett turbo guy tweaking on the latest Duramax, Casper the worlds fastest turbo LS1 car (at the time), Mike Moran machining parts, Kurt’s yellow car or turbo truck etc etc. Really too bad that Detroit blows and the place crashed and burned hard when the economy shit and GM started really falling apart. ---

Wiring Re-cap: To refresh your memory, this is what I started with: ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/BeforeLS1.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/BeforeLS1.jpg) ([http://www.nyspeed.com/showthread.php?82611-My-Build-Thread-LS1-FD-Its-Fast!&p=3132919&viewfull=1#post3132919](http://www.nyspeed.com/showthread.php?82611-My-Build-Thread-LS1-FD-Its-Fast!&p=3132919&viewfull=1#post3132919)) I pulled all the tape and loom off of the harness and inspected the wiring. I removed approximately 2 feet of charred wire due to a bad ground. I also repaired numerous holes in the insulation and replaced fatigued wiring. Once the harness was “repaired” I was ready to lay the harness back on the motor. In order to do this I de-pinned the ECU connectors, marked each pin, and bundled each separate connector harness. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311166.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311166.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311167.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311167.jpg) Once Drew and Mr. Donovan finished up their fab work on the piping I was able to relocate all the necessary sensors and O2 sensors. With all that laid out I measured the wire lengths, laid them down, and bundled the harness. Once the harness was the right length and had the proper wire routing I created a wiring board from it. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311220.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311220.jpg) I marked and placed guide points on key areas on the harness. This gives me reference for the next step… ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311221.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311221.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311222.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311222.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311223.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311223.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311224.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311224.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311225.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311225.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311226.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311226.jpg) Once the board is done I take the whole harness back apart and start all over. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311229.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311229.jpg) I first laid the common power wires and then the common grounds. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311230.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311230.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311231.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311231.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311233.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311233.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311234.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311234.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311239.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311239.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311240.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311240.jpg) _(Note - I did not get a picture of the wires soldered. This was to show how to properly attach multiple wires. These connections are stronger than using a solder splice.)_ The rest is to lay down the connector on the board in the appropriate location, cut the wires to the ECU, pin the wires, and add a length of new wire back in to re-connect. This needed to be done due to relocating the ECU to the passenger side kick panel in the A pillar. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311301.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311301.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311303.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311303.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311304.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311304.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311305.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311305.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311306.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311306.jpg) As I built the harness I slid shrink tubing on each wire group that I was able to get at in order to hold the small wrap. For the main harness I used a high ratio shrink tubing to hold all the secondary breakouts and for added strength. The final step was to tie the harness, run the actual wrap, and shrink the connections. ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311313.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311313.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311316.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311316.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311315.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311315.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311314.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311314.jpg) Then comes the final install… ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311325.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311325.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311320.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311320.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311319.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311319.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311324.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311324.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311322.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311322.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311323.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311323.jpg) ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311321.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311321.jpg) …and Done (^Drew already kind of spoiled it). ![http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311318.jpg](http://i160.photobucket.com/albums/t167/llorentz/NYSpeed/cougarspeed/Harness/061311318.jpg) Just for kicks…weight comparison for the LS1 harness.
