Hey guys I have a 1989 crx base shell I put a Si dash into and did a b16a1 obd1 conversion with a P06 chipped ECU. I hooked up the dash but am having issues with gauge lights not turning on, my tach isn't working and fuel/water temp as well... I used the stock dash harness due to the only 2 things that didn't plug into the dash were light dimmer plug and hazards plug(they are both different plugs). Swapped the Si dimmer and hazards with my stock ones. My dash harness is already wired to the ECU so I would rather not buy a new dash harness but will if I have to. Any feedback would be greatly appreciated.

Thanks all!

 

What year Is the SI dash. 90's gauges are different they will have pin-outs then our 89's.You will need to get a pin-out for your car and the pin-outs for the 90-91 crx gauges(If thats what you have.)Then just correctly match your wiring to work the new gauges.
