No tach, dash lights or temp gauge

[Loki]

Ever since I swapped in the new to me 7M into my car I have had no tach, temp gauge or dash lights. Speedo, fuel, oil and my swapped in volt gauge all work perfect. I'm not sure if there is something obvious that all three of those run through that I'm missing...?...

I've searched on here and found one mention of the dome light relay but checked it and it's fine and the dome light works. I'm really not the smartest when it comes to finding electrical issues but if anyone has an idea let me know.

Did you check all fuses? Did you swap from ge to gte? If you did swap from na to turbo the tach will not work because the gte ons a distributorless ignition system and requires a tach adapter from driftmotion. As far as temperature make sure that the sensors are plugged in and check wiring. I had a broken wire on mine when I had that problem.

Car was a GTE and I swapped in a GTE, I've checked the fuses I can thin of that would be related and have not found any that are burnt out.

Illumination, tach, and water temp are all on plug "A". It's worth a check.

I'm going to bump this back up.

Dash lights were the dimmer switch, still haven't figured out the temp and tach. I installed an Auto Meter temp gauge to keep an eye on that so haven't been too worried about it. I've recently had some time to start checking wiring and haven't found anything obvious yet but still need to do some more checking/testing.
