my rb20's gauges are totaly dead. im using the ka cluster with the RB20 tach. here is how it is hooked up.

yello/red wire on KA interior is hooked to yellow/red on the RB harness that the Fuel pump rely wire is on. i used the blue/black from the same harness and the same ground. those 3 wires are all that i tied fro the interior harness. the only gauge that works is speed. and i duno why it does i didnt even do anything.

i have asked carl H for help and we are both totaly dumbfouned. i cant get a lead on anything. nothing is working at all. on top of that i got this misterious MIss fire problem. and i havent the slightest clue how to fix that.

i am completely lost. i have pics for anyone willing to help i love the car its so fun but i just cant get my gauges to work and its making me insane. i pulled the swap off in under a week im so thrilled and i cant even drive cause i have no idea how hot or how fast teh motor is turning. its makin me sick. im so so soooo close.

 

I have a RB20 swap in my 89, my tach doesn't work but everything else does. It's not here today it got cold/icy and I'm driving the G20, but when it is I can direct you which wires go to what. When I spliced the single cam dash harness plug to the RB20 I followed the same dash wiring as heavy throttles SR swap. Just match up the colors. I'm using my AFC-2 as my tach right now I think maybe I damaged my tach putting it in because we wired another customers car the same way and it works fine.
