Went Single, question about wiring harness/fuel line. (pics)

Hello everyone.

I will start off by saying I have searched through countless build threads and searches, but couldn't find a solid answer.

I have purchased a single turbo harness from allrotor93. It is in great shape the only thing I have noticed comparing it to my stock harness, is it appears there are resistors wired into the primary injector circuits and not the secondaries. I have a picture and i would like like to confirm this. My factory harness has resistors in the secondaries ( I have stock primaries, and 1600cc secondaries). So would I have to take the resistors out of the primaries and put them in the secondaries? Also, since it was rewired, its impossible to tell which one is for the front injector clip and which is for the back. I assume it matters since there is the beige tape on the factory harness to denote which one is which.

Advise welcome!

Also with the fuel lines, It has been a while that they have been off, but if anyone could, from the transmission to the driver side of the vehicle tell me which line does what. I think the one nearest to the transmission (hard line) is the line that goes from charcoal canister to the vacuum line that has the filter in it. Also have a picture attached. I just want to make sure I am hooking my fuel lines up properly.

Thank you all in advance!

The resistors should be installed according to the impedance of your injectors. If you're using a powerFC, that requires high impedance injectors. If you are using low impedance injectors, then the resistors must be wired to those injectors.

As for your fuel lines I can't remember off the top of my head what they are.

Hope this helps

I do have PFC. I am not sure of the injectors since they were in the car when I bought it. They are stock primaries and 1600cc secondaries with resistors wired in.

The new harness has resistors on the opposite ones. I guess I should just take the resistors that were working fine on my old set up for secondaries.

If you are running OE primaries ditch the resistors. I dont know what secondaries you are running but if they are low impedance you will need resistors.

Ok thats what I was thinking but wanted to make sure. I will use the same resistors out of my old harness because I know they work!

Niw just need to figure out which fuel hardline is which. I think the middle line is for secondary rail and the one to the drivers side is secondary and the one nearest the trans is from the charcoal canister. But im not positive.

Fuel lines inside to outside (L > R in your pic) Canister > return (secondary rail) > supply (primary)
