Wire Plus EHC

Another post regarding EHC replacement....

Finished install and have a couple of issues. Tach not working, Speedo does up/down at startup but doesnt work after that, high beam indicator not working. check wiring several times and all is connected properly according to WP install instructions and wiring schematics from this site. Do you think these are all related and I need to replace the entire speedo w/Dakota digital or is it possible I just have some bad connections. Right before my EHC went out on me, the tach and speedo were doing some crazy shit...

Suggestions from the experts is greatly appreciated!

Did you get your ground wires grounded like the install says? I did mine and have no issues. Check all your pins are tight and try again.

I have a 04 so that’s about all the help I can be for a 07. Get your wire diagram and start tracing wires and check your resistance

Hope someone that has installed one in a 07 chimes in

If the speedo, tach and high beam indicator were working before the install then it's more likely an installation error.

I think you might have some wires switched.

When Seatmaker installed his he accidentally switched two blue or green wires. Recheck it.
