Default Can someone confirm these PINs for me

On a 96/97 harness, 4R = cyl 2/3 spark and 4N = cyl 1/4 spark (on the pin out it does not say, it just says ignitor).

Also, 1B = thermofan?

Just want to double check before I go start messing with wiring.

thnx.

1B is for the A/C fan, I think. Not sure which pin corresponds to which cylinders, though.

I just took a quick look at DIY's site, so I could be wrong. Idk where I put my wiring diagrams I had when I built my MS.

Just look at the colors on the wires to the coil packs at the plug and line it up with the diagram above.

4R = 2/3 4N = 1/4

On my car the fans were backwards from the above diagram. 1A = main cooling, 1B = AC fan. As far as I know the wiring harness was unmolested until I thoroughly raped it.

That's invaluable if you're going to be dicking around in the wiring harness.

I'm wiring a Haltech up. I have all the other wires noted, I was just unsure of the ignition outputs and the fans. If the fans don't work when the car is running I will swap those two wires and see if mine were somehow swapped as well.

I messed up the labeling. 1A is main fan.

Son, this thread is a disspoint. I clicked and expected debit card numbers and pin numbers to test at the local ATM, and all I got was some lame pinout diagrams.
