    Many thanks, hatzie! :bow:... I'll check it out. I just found the holy grail over on CC's Electrical Diagrams thread- that PDF with the codes and diagnostics on the 4L60E from those Brits (ATSG) :applaud:... replaced ground straps, found one broken, and giving the Ignition Switch another hard thought or two.... am going to run right through the initial battery checks and then the diagnostics for the 4 DTC's I mentioned above.
    Again, thanks...Have a great weekend. :woot:

    Guys why I wanted it to work because it blinks several times before it just stays on solid would you guys know of a bulb that would work on my truck and do what I want?

    I know Ebay has this blinker dealy but I want just a plug and play bulb.
    Thanks again! GMC

    I've looked through this thread and haven't found what I'm looking for. I'm looking for a wiring diagram for the fuel pump on a 1990 GMC S15. I also need to know where the fuel pump relay is on this truck.

    Such great info to know! Thanks chevychase! Just one question, is this for the ECM and engine wiring only? I just tried to look up a part number for 1993 and 1995 ECM and the site ( o'reillys I think ) gave different part numbers for the ECM's. I have a 1993 Sierra that I am wanting to upgrade the dash and other interior parts on.
    Again, thanks for your hard work!
