    my dash looks like this.
    i am trying to connect my new harness.

    where is the connection for the instrument cluster voltage regulator located?

    does anyone have a photo of the back of this cluster and/or a description of where it is?

    I cannot help you with where and how to connect but here are some pics I saved to my library. I think the one labeled is for a later, maybe 69-75isg CJ5 but may serve as some reference.

    Upon further examination of that photo you are correct. Sorry. Must have been removed on later era at some point. Someone should chime in shortly.

    The second posting should help with the rest. A couple good write-ups on his page.

    your jeep has been converted to a delco 1 wire alt. . so you wont have a voltage regulator the small white wire off of the alt. will hook into a purple wire on your intrument cluster

    Which voltage regulator are you looking for? There is one that is built in on the inside of the fuel gauge (can't see it) and also one inside the alternator (can't see it) if you are using the late model type alternators.

    The voltage regulator for the gauges inside the speedometer is part of the fuel gauge. That is why there is that jumper that hooks the 2 gauges together.

    my white wire is coming from the harness.
    there is a fat red wire that connects to the battery.

    It looks to me like you would connect your white wire to the terminal marked "Fuel Gauge Ignition Feed Wire (RED)" in Kevin's picture. This is the input to the internal voltage regulator in the fuel gauge. This was originally fed directly from the ignition switch, but it looks like your new harness fuses this (as it should).

    The heavy jumper from this gauge feeds regulated voltage (5 volts, I think) to the temp gauge.

    Maybe not a separate fuse, since I don't see a fuse indicated for this.

    I imagine you're asking for corroboration from someone else, but let me clarify my point.

    You need to correlate this with what you actually have. If your speedometer looks like this, and the fuel gauge has three terminals, and one of them is connected to the fuel sender and another is jumpered to the temp gauge, then the remaining terminal on the fuel gauge should have been connected to the ignition switch. This last terminal is the one you need to connect to the white wire in your new harness.

    If your speedo doesn't look like this, or something else doesn't seem to fit, give us some pics and we'll see if we can help sort it out.

    well yes.:)
    i got what seems like a few different answers along with pics that seem to prove there ISNT a voltage regulator at all.
    along with fuses that may or may not exist.
    so i am trying to get this clear in my head before i drive over to the shop and get confused again.:?R):beer:
    this reminds me of when i spent 3 hours looking for a fusebox.


    thanks for all the help once again.
    you guys rock!

    Bill, trust us on this :twisted:,

    There is indeed a voltage regulator for the instruments and on your vehicle it is incorporated into the fuel gauge as is indicated in the diagrams previously posted. You will hook up your harness's "white" wire to the point on the fuel gauge that sez "Fuel Gauge Ignition Feed Wire- (Red)".

    I'm nor sure where the confusion is coming from, it may be that due to the "general" nature of your replacement harness the instructions might make reference to a separate unit, but jeep stopped using that kind of design long before yours was built.

    The instrument voltage regulator should not be confused with the alternator regulator, that's an entirely different unit that, in your case, is buried within the alternator itself.

    As for the fuses, jeeps didn't have them originally but it looks like from the wiring harness diagram that it makes provision for them (most likely the rectangle on your diagram marked "8"), I believe that is what CO64CJ5 was talking about.
