Hey there
Firstly i had to replace my in dash harness and on my 92 civic si but the harness that i recieved was a ex harness off the same year model civic are these harnesses compatible . My brakes keep popping a fuse and my cabin fan ,fan spikes all my gauges when i turn them on.the harness is off a automatic and i have a manual does that make a diffrence aswell.:

 

the harness should be fine.. why did you have to replace it...

 

i cut it and was given the wrong info bad mistake paid for it i found the problem though thanks anyway
