Red ECU light stays on...

[govtworkhorse]

As the title states, the red light in my RB20 ECU stays on all the time. I am trying to track down a wiring issue that is causing a h3ll of a draw on my battery. I noticed this so I thought some of you wiring geniuses might know why that is. I was going to go up tonight and work on it but the garage is like 30 degrees I think and I figured I post this and hit it in the morning.

ok to fix this problem u need to unrap the wiring for both the green relays near the ecu, no turn the ign. on and feel for them to click, only 1 will be clicking, now locate the orange (iirc) wire running between the 2 relays and to the ecu, cut the wire that is running to the relay that IS NOT clicking. problem should be solved.

ok I'll try that in the morning and let you know whats up. Thanks.

make sure the white/purple wire near the passenger side engine bay fuse box is seeing switched 12v and not battery +.

So I cut the orange wire from the relay and it appears to have solves my problem. ECU light goes off when key is off and battery has held a charge of 12.64V since around 6pm. I will check it in the morning for the final test. If the car starts I'm happy.

I don't post on here much but I just fixed my car with this advice, you guys are incredible so Thanks! I had been unhooking the battery at nite
via quick lever on battery. I look to see my car running better too now since I hear the ECU learns how to act and behave as you go wich won't
happen if I unhook it every nite.
