ignition circuit relay isuuse

[alright2020]

ecu reads code 21..... i just put the motor and wiring harness back in.... the white connector to the ecu had all of the wires out of it and i had to put them all back in it... i matched them all with the ones of the harness it plugs in to... what else causes an ignition circuit issue? is there any way to figure out exactly which wires go where? there are two yellow wires with green stripes... idk?

you checked the ptu? thats generally what triggers the code 21

why was the harness depinned? there is no reason to depin the harness unless some bonehead tried running a crappy piggyback system

de pinned to go through the firewall easier i guess... it was the ptu... i was kinda runnign on cruise control from lack of sleep and couldnt figure it out and just gave up for the night... first thing i did is check to see if anyone replied.. noone did then i looked at my ptu and it was unplugged on one side lol
