Turbo setup questions
so im adapting an s4 n/a harness to work with an s5 turbo motor. I of course am changing to new s5 injector pigtails. My question is: how do i know which injector clip on the harness goes to which injector? also there appear to be 6 injector looking clips but there obviously only four injectors are the other two for emissions equipment that i no longer have? how do i tell the difference between the 6?
Also i deleted my BAC valve, cant find any info on if im supposed to cap off the coolant lines at the thermostat housing and rear iron or run a line between the two?

The BAC valve clip is blue... I THNK. Which would mean that the water thermo sensor clip would be green. I cannot remember. You should be able determine which is which between reading the wire colors in the series four FSM.

so the fsm isnt as helpful as i thought it would be. if it says injector (f-s) i assumed that meant front secondary, correct? LG/W and B/Y means? are those the colors of the wires? light green/white? black/yellow?
sorry if i sound like an idiot just not sure how to read it. and yes i read the intro that says how to read the fsm...

The Factory Service Manual is pretty helpful when used properly.
I have had mine capped for quite some time now. No issues.
Correct. (F-S) Front Secondary, (F-P) Front Primary, (R-S) Rear Secondary, (R-P) Rear Primary
Wire colors are in the FSM somewhere. I know that in the '87 FSM they're in section 15 "Body Electrical System; Introduction" (15-4)
CODE > COLOR
B > BLACK
Br > BROWN
G > GREEN
L > BLUE
Lb > LIGHT BLUE
Lg > LIGHT GREEN
O > ORANGE
R > RED
Y > YELLOW
W > WHITE
Examples: BrB is going to be BROWN with a BLACK stripe. BW is going to be BLACK with WHITE stripe.

Thank you again dwb87. I was up late last night reading and saw that I have to combine all five wires together that go to the low impedance box?
And how do I determine the polarity of the injector pigtails? And does the 87 low impedance harness have the same color wires that I see in the 88 fsm? Can't locate the early 87 fsm :/

Figured that stuff out, Haynes Manuel came in handy for once as soon as I found a microscope..
New question, I'm concerned about having too much fuel pressure at idle with the walbro 255 and stock fuel rails, pulsation dampner, and stock fpr.
Can I run an aftermarket fuel pressure regulator with my stock fuel rail set-up?
