RJansen658 Posted March 18, 2007 Report Share Posted March 18, 2007 Hey guys... I just finished swapping a 91' CS Digital UB3 into a 93' CS that had the Base cluster. I used the home pages walkthru, and got everything working correctly. I only had to run 1 wire for the tach. After I was done, the was 2 wires left that weren't used. 1 was the white wire that was for the base clusters tach, and the other was brown, I don't know its purpose. My question is... The 91' that the UB3 came out of had standard HVAC controls, the 93' that I swapped it into has digital HVAC controls. I read somewhere that the e/m switch on the cluster can also make the digital HVAC change from english to metric. I see in the pinouts that pin D9 (LT BLU) E/M OUTPUT TO HVAC & DIS should be run to the HVAC unit.... Has anyone else done this yet? I know its a lame feature, but I wanna make it work if I can. Cmon CrazyK I know you must know what I'm talking about... Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted March 18, 2007 Report Share Posted March 18, 2007 hmmm, i didnt know that the ecc changed, never cared I guess. I know that you can link the UB3 with the DIS, but I didn't know about that. The extra wires are for the security, and something else. I have two, but the other is for the airbag light, which since you have a 93, that wouldnt be there Quote Link to comment Share on other sites More sharing options...
RJansen658 Posted March 18, 2007 Author Report Share Posted March 18, 2007 Ok I have been working on getting the ECC to change to metric for the last 3 hrs... I can see on the ECC screen that it is capable of displaying farenheit and celcius. I thought that since it is prewired for a hud, I could simply attach into the hud harness's e/m wire and the ECC would be linked... it wasn't. The ECC has 3 plugs, each with 7 wires. Each connector is a different color. Black, White, Gray. Out of the 3 plugs, there are 3 LT BLU wires. I'd hate to have to just start grounding out wires.... Could someone post a pinout for a 93' Cutlass Supreme electronic climate control? Quote Link to comment Share on other sites More sharing options...
RJansen658 Posted March 18, 2007 Author Report Share Posted March 18, 2007 WOOT! I got it, all I had to do was run a wire from pin D9 at the instrument cluster to pin 11 in C2 (Black Connector) at the back off the ECC. If anyone is interested here are the 89-93 CS ECC Pinouts... C1: 7. LIGHT GREEN/BLACK – DEFROST solenoid control 8. TAN – A/C solenoid control 9. PURPLE – BI-LEV solenoid control 10. LIGHT BLUE – RECIRC solenoid control 11. LIGHT BLUE – Temp door motor control 12. PURPLE/YELLOW – radio for dimming of the display 13. GRAY – light switch for illumination 14. BLACK – ground 15. Not used C2: 7. BROWN – Air temp door variable feed 8. Not used 9. DARK GREEN – Inside air temp sensor 10. LIGHT GREEN/BLACK – outside air temp sensor 11. Not used 12. LIGHT BLUE – rear defogger timer relay 13. LIGHT GREEN – A/C request (goes to ECM) 14. RED – HEATER Solenoid 15. GRAY/BLACK – to blower controller (C1- C3: (Black Connector) 7. BLACK - Ground 8. ORANGE – to ELEC fuse (hot at all times) 9. ORANGE – To ALDL 10. DARK GREEN – to ALDL 11. BLACK – GROUND (this is for the E/M switch. If you ground it, then the display will be in *C, instead of *F. Either connect it to the E/M switch, or just straight ground it for canadian cars) 12. PINK/BLACK – CLUSTER fuse (hot in run) 13. YELLOW – Sensor Ground for inside, and outside Air Temp Sensors 14. PURPLE/WHITE – rear defogger ON indicator 15. PURPLE – to blower motor Quote Link to comment Share on other sites More sharing options...
