lighting issues

[tsupra89]

ok my name is travis and i just started the forum. i have recently replaced my engine and transmission. in my 89 toyota supra T and my lights are wanting to do something strange that i have never seen before ok.


here is how i slove the problem, when i take the dome fuse out of the engine panel the lights work perfect and the headlight motors and all that and the horn, well when i put the dome fuse back into the panel the lights go haywire. if i turn them to the off position on the multifunction switch the lights turn on and vise versa. and the motors wont work and my horn wants to stay on all the time. well i was wondering if anyone has run into this problem and if so hit me up with some info please.
