Hello all! I’m new to the site and hope to learn all I can about these trucks.
So recently I acquired a 1990 2500 (6 lug) manual trans from an auction. I wasn’t familiar with these trucks, but it was a pretty good price and I needed a truck. Good news, it runs and drives and is fairly clean. Bad news, I didn’t know at the time that the 454 (carbed) was swapped into this truck so who knows if everything was done correctly. On top of that, it has the grill and interior from a ~1995 model. The swap seems to be very well done, but my gauge cluster doesn’t work except for the volt and temp. I assume they just didn’t attempt to try and wire it correctly and was banking on it just working when plugged in.
So, does anyone have any information that would be helpful with my situation? From what I understand the ECM would normally be required for these clusters, but since it has a carbed 454, doubt that’s an option. Would it be possible to just hard wire all the wiring to the cluster plug and have the gauges work?
Sorry for the long post, but it’s a pretty complicated situation to me so I just want to try and give all the information I can.
Any suggestions or diagrams are greatly appreciated!
