just match the colors up its very simple you should have three or four wires left that you will not use just tape them up so you have no arching and the sohc ecu will not work on the dohc you must use a 91-94 dohc ecu hope this helps

its all good i was really lucky when i was searching for the info it took me a month to find all that i have

you do know that you have to get a 91-94 maf and distributor for it to work

i supose your talking about the water pump pully/belt you will need to get a dohc p/s pump and block off the holes some how then you will be able to get it tight
