hey guys. running ka-t, need help with electrical

[klattr1]

hey, i swapped in my built motor today. I started it up and it ran fine but no interior features. No power windows, no tailights, no cd player, headlights work though, no locks, no RPM's, no speedometer, etc.Can u think what would cause this?I checked all the fuses in the cabin and even the smaller ones in the black box in the engine bay. Could it be just a ground? The ecu is flashing no codes. I looked at the harnesses and all of them seem to be plugged in. Its just wierd, like all of the electrical stuff in the cabin doesnt work. Is their a main fuse for all of those features?

there is two plugs on the ecu... did you get them both, there is the main harness which goes into the whole ecu and then another harness which plugs in above the ecu, i would make sure you got that one in.

thanks for the info.i ended up looking at the fuse box in the engine bay and it looks like the 100 amp main fuse is blown.Im going to replace that now.

i hope that does the trick.

the 100 amp fuse fixed the problem.Everything is running great.I gotta wait until its broken in and when I can afford dyno time before boostin.
