I was tearing apart my wireing harness to see a large mess. For all you guys with sr’s in your cars i recomend that you replace your coil pack grounds. I took mine apart and seen all 4 wires crimped together and covered with tape and then it bolts to the back of the block. So I took mine and sauderd a larger 16 gauge wire and heat shrinked it and dubed them to 2 conectors and relocated them to the intake. Doing this I also recomend doing your ground from your batt to your intake and to your frame rail in a 2 gauge wire with some good conectors so you dont get too much resistance and better continuity. Doing this gives you better, more crisp throtle responce. I will post some pictures later. ---

Well it only took me about a year to get these pictures up but i finally got a camera a computer and photoshop In the first pic you will see the whole coil pack harness. In the second pic you will see where i cut off and extended the wires. In the third picture you will see how i dubbles up wires to 2 hoops from the coil packs. I just attached it to the intake manifold where the other grounds from the other harness goes to. I made sure the are was clean and had no resistance. This mod gave me a little better throttle responce and better spark at higher RPM’s Pic 1 ![http://img86.exs.cx/img86/3029/coilpackgrounds0017td.jpg](http://img86.exs.cx/img86/3029/coilpackgrounds0017td.jpg) Pic 2 ![http://img86.exs.cx/img86/8899/coilpackgrounds0029ja.jpg](http://img86.exs.cx/img86/8899/coilpackgrounds0029ja.jpg) Pic 3 ![http://img86.exs.cx/img86/3382/coilpackgrounds0030bt.jpg](http://img86.exs.cx/img86/3382/coilpackgrounds0030bt.jpg) ---

Why did you crimp the connectors on? Why not take off the plastic crap and solder the connectors on? That way they will resist corrosion better, and provide a more secure connection. Go over the top with gold plated terminals used for car audio applications, and silver solder. I always solder all my terminals on, and my wiring rarely fails on me. Just my 2 cents. ---

There is salder in there you just cant see it and there was no resistance with those shitty conectors. I just was doing it for now cuz I was going to redo the whole harness during winter and was getting the nice conectors then 😃
