Ok guy I bought 90xj with already swaped sbc looks lk it caught fire on first ride after swap I think it did cause no pressure regulator on fuel and no return but here's the deal it burnt dash gauges under dash some and wiring on fire wall is toast so I have tore it out hook 4 prong universal switch up temp under hood wired distribut up just enough to start see what I had I got painless wiring kit with 21 circ what would u guys do to get it going ?? Replace factory wiring or aftermarket key switch lights and exetera and painless kit

 

Aftermarket, without hesitation... The steering column is straight GM; easy as pie... While I'm not sure I'd pay the price, I'd love to see an aftermarket harness for XJs, but that ship has sailed.

 

Thanks man I already have some sort of wiring lk a painless kit I'll post pics when I get a chance s ok the whatwhat to about the steering column being gm I'll get u some pics appreciate it time in
