Unknown Plug On Steering Rack

[mrsr32]

hi

could someone please tell me what this plug is for? looks like it belongs to the steering

i don't have a plug in my loom to go into it, but i do have a light blue and black cable that has been chopped close to it, i'm assuming the plug has been hacked off.

sorry for whoever the original picture is.

Power steer switch.

Sends a signal to Pin 19 at the ecu to bump up the idle when driving slowly/parking etc.

Keeps you from nearing stall when taking low-speed, sharp turns where there's no throttle but strain on the engine from the PS Pump

ah that explains a few things then, might just try to see if i can get some crimps to terminate on it as i don't have the loom plug.

does anyone know which connector is which? i have one blue and one black cable to plug into it.

Do some continuity checks.

To bump up the idle, Pin 19 goes to GRND.

So I'd check if your black wire is a GRND and if the blue goes to Pin 19 at the ecu.

^ Again, jiffo beats me to it.

you could pop one end of the multimeter in Pin 19 of the ECU and see if it's grounded through the ECU or a 12V feed through it. If it's grounded through ECU, the other just goes to a constant 12V feed and it activated by ground through the ECU, visa versa if the 12V feed comes from the ECU.
