i got an ex gauge cluster from an ex civic to put into my 1995 civic dx coupe. i was fine until i discovered one of the 4 wires in the back are different. the gauge cluster from the ex is a manual one and my car is an automatic right now, i'm building a motor now and don't plan to swap it in for about 2 months. the yellow and 2 gray wires fit perfect but the green wire on my wiring harness is bigger than the hole in the back of the ex cluster. HELP!! what do i do? i have a harness from an lx parts car (its got the right size plug for the green) but i dont know where to cut wires and where to connect them. i ran the car and the tach works, speedo works, everything works except the turn signals. they won't even come on on the outside. if you can help, please do.
