93 1500 w/ 5.3L & 5 speed swap

[mctavish.95]

Hey i just did a 5.3 5 speed swap in my 90 gmc 4x4, i was wondering if you did anything with your speedo because i got everything to work on the cluster except for that? Thanks

What did you change that the speedo doesn't work?I used a tremec 3450 5 speed from Rockland gear and my old speedo connector wouldn't plug in so i cut it off and found the right connector for the tranny and wired in the new connector.Works great.

I didn't change anything, I used the stock transfer case for the truck I just wasn't sure if I needed to change anything for the speedo. Just weird it stopped working when I put the 5.3 in

I'll love you forever if you go over here and answer my question about the wiring connections you made into the truck harness.

New here, I was wondering if I could get a parts list, I'm looking at doing this swap for my 98 Silverado 4x4 with the 3500 and am not sure of things like what I need to do wiring wise and like what you used for a fuel system, my 5.3 motor is out of I think an 01, any help would be greatly appreciated thanks

Okay i am using the PSI harness also. It had the one wire for the speedometer and one for the tach. I'm working on a 94 truck so my problem is I don't know what wire to tie the wires from the psi harness into behind my cluster. Help me please!! Lol

White wire that went to your distributor is for the tach and the speedometer I connected to the drac box behind glove box. You need to do a search for the wire colors to use for the speedo.
