No name LMC dash cluster ???
I can’t get the tack to work with my LS 6.0 swap. I called LMC to see who makes the cluster and try to find a wiring diagram but since I did not buy it from them they will not help me at all. I called New Vintage Gauge and they said it’s not one of theirs. The tack will only send a V4 signal. I have had the truck in the shop for 3 weeks now so any help you can give me would be great.

Re: No name LMC dash cluster ???
We need more info like what engine do you have, but i can give you some tips. Do you have it hooked to the white wire coming from the PCM that gives it a signal? For the 4 Cylinder tach signal, you will need to change the tach resolution from 6 to 3 in the tune, some sort of tuning software will be required. Also, if your PCM is newer than '03, you may need a pull up resistor to strengthen the signal enough for it to work.
