FASTMR2 Posted May 5 Report Share Posted May 5 I have 93 MR2 that has link G4x with a can keypad that I'm trying to configure so I can make the keypad turn on my Intercooler fan, I have already wired the relay and attached the 85 terminal to a DI pin on the expansion loom of my ecu, cannot get the ecu to ground the terminal. I have tested the wiring and it works. but cannot get the ecu to ground out the DI terminal. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 5 Report Share Posted May 5 the 85 pin on the ECU needs to be connected to an Aux output not a digital input (DI). Any of those spare Ignition pins on the expansion plugs will do the job. Quote Link to comment Share on other sites More sharing options...
FASTMR2 Posted May 5 Author Report Share Posted May 5 the 85 pin is for the relay, I only have one expansion loom, and only have 4 wires not being used 2 DI and 2 volt Quote Link to comment Share on other sites More sharing options...

You need to use an output to control a relay. Quote Link to comment Share on other sites More sharing options...

FASTMR2 Posted May 5 Author Report Share Posted May 5 ok how do you attach that pin to the can keypad to make it ground out the fan relay Quote Link to comment Share on other sites More sharing options...

If you post the File we can help you setting up. Quote Link to comment Share on other sites More sharing options...
