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.
Yes, you still need one.
I have ran an inline cable drive VSS adapter with the 7427 and without the VSSB, but you're better off wiring it up right. Without a VSSB/DRAC, the speed signal going to the PCM can be off by quite a bit which can affect how the TBI performs as well as shifting/lockup. It's only a few more wires and the module isn't too difficult to find.

Thanks for the information, I'll start my search
Going to go dumster diving at the junk yard can I use any VSSB/drac with 14 jumpers?
