Does anyone know where the ECU hides in a 91 RR?
Thanks

Now, where is that bugger on those trucks...

...ETM says "Drivers side above lower dash panel"

It may also be handy to know...

...part number may be printed on it, PRC5060, I believe the unit is black.

Has an white(?) 8 pin connector plugged into it.

Pin 1 - white with yellow, supplies power from cruise switch (fuse C5 - 10 amp).
Pin 2 - red with white, input from set/accel switch.
Pin 3 - purple with green, cancel signal from brakes, via relay.
Pin 4 - black with red, vaccum pump motor control
Pin 5 - yellow, speed input.
Pin 6 - blue with white, input from reset/decel switch.
Pin 7 - black with yellow, vaccum vent control.
Pin 8 - black ground.

Good luck!

Later,
Don
