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.
