Hello I have a wiring harness from a 1995 suburban
I have all new glowshift elctronic guages
Im Trying to wire up my vss to ecm and guage to ecu my wiring harness wires from the VSS do not match my ecm wire colors how should I proceed? And are these the two wires I need to connect to on the ecuF-12. BRN. Transmission output speed
F-13 DK BLU VSS Signal

Normally there will be a DRAC or VSSB wired in between the two F12 & 13 would go to the VSSB and so would the VSS wires along with a +12v and Ground wires. The VSSB will have an output for your speedo as well.

That's what I was afraid thank you
I replaced my speed meter with a glowshift speed meter it has the speed adjustment on the guage it's self does that take the place of the VSSB? If so does the ecu need a corrected signal from a VSSB?
Does the gauge have an output for the PCM?
It's a one wire connection and the instructions said to splice into VSS sensor signal wire. it has a wave adjustment for the speed meter it's self I was concerned about the connection from the VSS to the ecm. I have the speedmeter covered trying to figure out if I need a VSSB for the ecu to read speed and control the transmission.
