YJ underhood wiring diagram that isn\'t junk

So I am trying to clean up the mess of wires under the hood of the wifes 92 YJ that is converted to a sbc. The Haynes (i think) book is a joke for the wiring colors and where they go.
I have the jeep to fire and run off the key, lights, turns, charging blah, blah, blah, but am trying to get the engine gauges working and fuel gauge working, but all i have is wires coming out from the firewall.
Anyone have a FSM scanned or diagram online I can look at?
TIA

Re: YJ underhood wiring diagram that isn\'t junk

pb....I feel your pain.....I'm finishing up a SBC swap into my 84....I used the original SBC wire harness...I only had a few wires to hook up after I striped all of the other stuff out that was related to the original computer.

I used my original gauges and just added the original sensors on the block. There is a plug just above the oil filter that you can tap for oil pressure. There is another plug on the right side between plugs 6 and 8 that you can plug your temp sending unit into. If your SBC is anywhere in the 88-95 range, the tach will be the white wire near the computer connectors.

I'll take a look at my manual to see if it covers your year.

No doubt, Jim Lou will have it....or Leve....

BTW...wish me luck....I take my jeep to the smog ref in the morning.

Thanks, I have the engine side figured out no problem, mainly need to find out what color wires used to hook up to the stock stuff, i.e. temp gauge wire color, oil pressure, etc.
