1986 IrocZ MAF burnoff relay issues

So I've searched for an hour or so and all I find are diagrams where the relay for the burn off has 4 wires, my relay has 5 wires A-E. A and D have power when the vehicle is running. E has power all time. B has ground all times. C has ignition power. Does this seem right? I thought the computer controls ground to come on right after the vehicle ignition is off. All testing during closed loop only have code 36.

Re: 1986 IrocZ MAF burnoff relay issues

So the po must have moved the wiring harness around for the burn off and the fuel pump. I tested the burn off per the troubleshooting chart and everything was working correctly. Looks like I need a new computer to fix this.
