Wiring for Speedometer help!!

[xXxSilveradoxXx]

I'm wondering the same thing..... c'mon, somebody post up!

Hook the VSS up using the Nelson harness and then hook the wire from the gausges to the C2 red connector Pin 50 dk green and white stripe 4000 4K and that should fix the speedo. What year model is your truck, this is for 96-2000

Ah hell, I just read 89 but it's probably close. I can tell you tomorrow though unless someone beats me to it.

The thing is my VSS has 2 wires going to the stock cluster and the nelson harness has one wire. Thats my dilemma

I'd like to have the speedo wired up before I drive it, but we'll c!!

Just hook the one wire up (Green) to the pin I mentioned above and you'll be ok, the other wire is another VSS signal for cruise, the radio or something else.

Our problem is that the DRAC/VSS buffer is built into our cluster.

I'll try it, but Im almost positive it wont work. I have the moonie gauges and they have the drac built in it. It has the two wires from the original 700r4 speed sensor that goes directly to the cluster then comes out of the cluster and goes to the comp., cruise.
I called nelson performance and basically they r guessing too. and said to try and hook there one wire to one of the two wires and try it. If it doesnt work try the second wire.
So I'll try urs and his suggestions and go from there.

Thats what im saying! And I dont think anyone has done this swap with our instrument cluster.
