Thread: Freaky 3.5EFI runs without ECU ???

From memory there were only about 6 wires to connect!

I found a few good websites with wiring information.

Have a look here. Rover 14CUX Hot Wire Mass Flow EFI: Service and Troubleshooting down the bottom is a guide to wiring pins on the ECU. As far as other wires I just spliced appropriate colours under the dash for oil pressure, water temp and battery light. The temp guage isn't quite accurate (reads high) and it is on my to do list.

I wouldn't hesitate to do it again. My original plan was to keep all the 3.5 stuff including timing cover and ancilliaries, but I am glad I didn't.

The actual wiring to get it to run took about 2 or 3 hours.

No worries, if you have a search I have a few threads from when I did the conversion too. Got a few pics in there as well. Feel free to ask any questions.
