how it sets in my shop.

this is my first inline6 swap, ive done tbi and tpi, and ls1 but never this
so help is needed,
i got the harness all in and so far working, the engine harness i guess is out of a newer wrangler (93 i think), i have power but the starter dont work, and i dont have power to the fuel pump,

i just picked up a e2000 inline fuel pump from a ford to do the swap, so i dont have to deal with the intank crap,
and i have this plug under the dash i dont know where it goes..
Image
i think i might have to switch out the harness under the dash to get everything elce to work.. :D

Do you still have the 4" springs laying around? Any idea what brand they are? I may be interested in them...

Got the jeep runnin and all together.. the 94yj to 89yj swap was kinda cool.. only needed to one one wire for the ign switch. And one wire to power for the fuel pump..

I ran a e2000 pump inline with a gm fuel filter. And it work ok. Think i might need to add a helper pump later. But the motor runs and sounds good. Pretty quiet.
The 87 harness already had the fuel pump wiring just needed to add power. It was nice..

Now some gauges dont work due to the 94 to 97 harness.. so custom gauges it is.

Now all thats needed.. front d60 hubs. Brakes.. install front drive line. Lift rear. Heater core Gauges..

Now to the brakes.. the yj mc is not enough to lock up the dual piston calipers f/r so i am thinkin of the f350 mc i was told its a straight swap. Little grinding. Then some adapters for the lines.... Ill post pics when i get the parts
