    i went to my local library and copied the electric diagram for my Blazer...she is a 90 but the manuel was for an 89, I hope it doesnt make much of a difference. It makes reference to I/P...for example 'splice 303 located LH side of the I/P'
    What is an I/P?
    Thanks for any help

    Be sure that you have the schematic for the R/V series trucks. That was the Blazer/Jimmy in '89. That year the pickups had the C/K designation and the newer body style. There are also some differences in the harness and other things, even though they were built in the same model year. /forums/images/icons/shocked.gif

    It can drive ya kinda crazy when you're looking for something that isn't really there. /forums/images/icons/wink.gif I've got the '87 shop manuals and have caught myself looking at the wrong pages in the wiring diagrams a few times. /forums/images/icons/shocked.gif

    On the later car manuals, I/P is actually the connector that some of the ALDL wires go to, then from that connector, to the ECM. Other wires such as ECM 12V also route through there. (So from ALDL, to I/P connector, to the ECM plugs)

    Instrument Panel might be correct as well, but my '88 car manual I *know* has the I/P connector as the one for ALDL/ECM.
