Alright,

So here it is, my speedo and tach doesn't work after a b16a2 swap into my 97 hx. I used my 99 SI engines harness and its ecu. The Si had 2 engine plugs on the harness and then one coming from the dash. Well the 97hx harness had 3 engine lugs and the same dash plug from the si bu it goes with the cut engine harness.

Would this plug bw the issue and how could i fix it? The si has it in the dash and the cut up 97 hx harness ahs it running into the engine bay.

What gives?

Please help asap

 

check your backup light fuse, the tach and speedo is connected to that fuse, it might be blown, had that problem couple of months ago, it was a fuse
