st165 speed sensor wiring.

Postby outinnowhere3193 » Fri Jun 17, 2016 1:46 am

I am in the middle of redoing the car and when I pulled the engine I realized the reason the cruise didn't work was because the speed sensor wasn't plugged in. So I looked for the plug and can't find it.

When I look at the ECM is shows SPD for the speed sensor but if you follow the wire in the harness it just goes from the ecu to the connector that goes into the dash wiring. So where does the speed sensor actually tie in at or can I simply just run my wire and tap in with this one and provide it.

I've pulled wiring schematics but I can't find the wires matching the colors. Anyone know exactly which or where the cruise control box is?

If I remember correctly this runs off a little box / adaptor connected to the speedo cable ....
