Gauge cluster issues after 5spd swap, 240sx

[Newcastle82]

Hey guys,

Alright, here's what is going on.. I just picked up a '93 coupe, it was gorgeous, snagged it for $1250. Only problem was the automatic transmission. So I pulled it out and converted the car to 5spd. I've done this swap a few times before and never had an issue. I do now.

The car starts, runs, and drives fine. No hesitation, no apparent loss of power, and alll the lights work - backup, brake, running and headlights. Runs great. My issue is with the passenger compartment electronics. The gauge cluster won't light up, tach / speedo won't work, clock won't work, headlight control switch won't lower the headlight motors, and the dome light isn't coming on.

What the hell is going on? I used the transmission from a '90 car, and I was lucky because it came equipped with the factory transmission / alternator / starter harness. Everything seems to be plugged in just fine, but maybe the '91 + transmission harness is different in some way?

Please let me know your thoughts, I have got to get this car down for a smog / safety inspection ASAP and it won't pass visual without a working multimeter. Please help!

you might of snagged something while you were under the dash. Check your relays and fuses on the driver side kick panel.
