1995 C2500 ls1 swap

[chvy=power]

Awesome....so say I swapped in a 96+ cluster, do you happen to know if I can just hook the white tach wire from the new pcm to the back of the cluster? If so do you know what color wire I need to hook to and what pin location it is?

Here's the only vid I have for now.... Took this right before I did the exhaust. This is open headers and the tune was way off. She smooths out and starts hittin one wicked lick

The cluster is a direct bolt in, you don't change the connector so the wires all remain the same. Yes, you can hook the white tack wire to the wires going into the connector that goes to the cluster. According to the wiring diagram from alldatadiy, and how I wired mine, it's the white wire in pin #6 on the back of the cluster. This white wire originally came from the ignition coil on your TBI motor. If you still have that wire in the engine bay you can splice into that and there will be no need to go into the cab.


Here's some info on the police cluster, it's hard to find and you will need the jumper on these. To be safe just look for a 96-97 cluster then it should be a direct swap IIRC, but do some searching first don't take my word for it.

Hmmmmm I hooked to the white wire that was originally for the coil and my tach doesn't work...Maybe I messed up somewhere. I'll ohm the wire under the hood and at the cluster and make sure I hooked to the right wire.

Yeah, just check for continuity. You can see the diagram has the tack connected to the ignition coil. If it ends up not working try this:

This is awesome! Yeah, we need some videos...in cab video shifting as well. Does the 95 2500 have the same updated interior as the 95 1500? Or is it the older interior like the 89-94 1500 interior?

[chvy=power]

Yea mine has the updated interior. Once the rain quits I'll get some vids. It's supposed to rain solid for like a week

Damn. Was hoping you were gonna say the old interior like I have and it was a direct swap because when I searched it seemed like a 95-98 cluster swap into a 92 was either not doable or a huge pain in the ass.

I'm looking at this one:

It will display A/F as well

[chvy=power]

oh lawd at the price tag on that bad boy! Ya that look like a nice little set up tho

[Skylark]

It will display A/F as well

I don't see a/f listed. Where did you spot that?

[GreyChevy]

Yeah, that's why I was hoping the 95+ would swap right in cause that bastard is expensive!

To get it to display a/f or a bunch of other readings you need an expansion module:

Still requires a wideband but would display on the dash.
