87 Comanche 2.5 to 89 Comanche 4.0 swaps

[MattK]

Hey guys, I’m in the middle of my 4.0 swap and I’m having issues with no power to the back of the truck. No brake lights, no power to fuel pump. And starter relay just clicks when I try to start. I jumped the starter solenoid to hear it crank but obviously not delivering fuel and no spark. Any advice would be appreciated. The gauges twitch when I bump the key and I have power to the headlights but that’s about it.
