SOHC to DOHC

I am looking for a website of links to a turtorial on how to make my 89 coupe with sohc to a dohc with power steering. can anyone lend a hand. i tried the search bar but didnt come up with a whole lot thanks.

It’s easy, I’ve done it a bunch of times. What do you need to know?

yo im doing this too, so would a kade wire that connects to the ka-e pc work??

i need to know how to make the wiring harness the rest i think shouldnt be to hard.

You just use the DOHC engine harness, everything plugs in and works except the plug above the ECU by the glove box. You have to put the one from the SOHC harness on, wire colours are the same so just connect the same ones together.

sweet thanks

i was left with 2 green wires un connected on the plug side and about 5-6 different color wires on the ecu end what do i need to do? ones purple 2 bluish 1 light aqua a grey one and ithink a red one with yellow line

i know you will have left over wires from the swap. there for diagnostics i believe
