    Making an external slave work with a Ls?

    Over the past few months I’ve been swapping an lq9 into my 95. Finally got to where I thought I was really close just to bolt up the trans and have the slave cylinder interfere with the oil pan. So now I’m at a crossroads, either swap in a 96+ nv3500, convert mine to internal, or go to a t56...

    95 Bulkhead connector on the firewall pin out?

    I can’t seem to find the pin out for the bulkhead. I can find 96+ but nothing before that. I would chase wires from the original harness but my dumbass cut a lot of them thinking I didn’t need them. It’s the last part I have to hookup to my Ls stand-alone harness.
