Connectors near ECM Unplugged, VSS, Speedo
89 Formula 305 TPI
I have been troubleshooting my speedo/VSS, neither has power.
Near the ECM, from the wiring harness there is a two pin connector for the VSS and a multipin connector which has the speedo wire in it.
Both are unplugged and I do not see a way to plug them into the ECM/ ECM harness, is there a module/connector I am missing??
Two connectors at top of image.

Re: Connectors near ECM Unplugged, VSS, Speedo
Looks like you're missing a DRAC module. This converts the 4x signal from the magnetic VSS to a 2x signal that the ECM can use.

Actually, does anyone know if these modules differed between transmissions/engines/gear ratios etc?
Because it looks like I'll be hunting in the junkyard.
Thanks,
Dave
