s4 turboII injector wiring harness questions
 

I have searched for the past few days and haven't found anything that answers my questions so far.

I have gone through and removed the rats next, rebuilt the fuel system and need to know what plugs go to what injectors on an 87 TurboII. (done about a year ago)

(NOW) I am picking this project up after almost a year of it not being touched.

I have been looking for a diagram of the wiring harness or even photos of someones engine bay with the manifold removed. Haynes manual seems to be useless for this. I will upload and add some photos as soon as i can.


Thanks for your time

do you have a haynes manual? the diagram is in the back of the haynes manual.

I have been through the digrams in the back of the book.

If you see two Injector plugs close together,they are for the Primaries..the secondaries are separated by about four inches on the Harness.
the Injectors Batch fire(both at the same time) so you won't be switching Rotor one and two up at all.
IF you get the car together and start it up,and Have the Problem of "lightly touchin the gas and It Dies" switch the injector wiring..(put the Wires that WERE on Primary injectors onto the secondaries and vice versa).
I know this..BOY!, I KNOW THIS!..it stumped me for 4 months!

there are 2 branches, each has 1 second and 1 primary. the branch that has the coolant temp plug is for rotor #1, while the other one is for rotor #2. it's actually kind of hard to hook it up wrong.

If you start at the ecu side the first two injector clips with the shorter wires go to the primaries and the ones a few inches down the harness with longer wires are the secondaries. Atleast that's how I hooked mine up and it runs good minus my vacuum/boost leaks (project in progress).

Long time since this project started and its time to finish it up. I have attaced a video at the bottom. my big issue is that out of the 6 injector type plugs what 4 go to the injectors and what are the other 2 for. If anyone can list what these plug into in order it would be great. 4 of the injector type plugs were damages and new ones were soldered in so the lengths aren't the same as stock.

Ok, you've got two green plugs and 4 brownish plugs. the green plugs are for the BAC and the water temp sender. For the other plugs, you have two that are short and two that are long. the two long ones are for the secondaries, the two short ones are for the primaries. As for the two green ones, Im pretty sure one will reach the back of the water pump and the other won't. its pretty straight forward fromm there.

I just did this today :-)
