oil level sensor question E to I harness swap

[Bretts85E30]

ok so as the title says im doin the e to i harness swap and the biggest problem i have is finding an early eta with the square plug i got lucky and found an early m10 318i snipped the fuse box end off and got it pretty much all wired up

but the only thing that the harness is missing is the 2 wires for the oil level sender... now my sender doesnt work anyway and the harness i have is plug and play for the sender do i really need it wired up? or can i get by without it til i can get my hands on the correct one or just goto the jy and try and remove the pins from a similar harness so i can add em to the harness.

any help would be appreciated this is the c101 that im talking about if i was unclear lol

Are you saying that the engine harness you are trying to use has a square C101 plug? That would be an ETA harness and you need the harness (which has a round C101) from an M20B25 for a e to i swap.

i have an 85 eta and i have an 87 i harness the square c101 i got from the junkyard to make an adapter was from a 85 318.

the only wires the square plug is missing are pin 2 and pin 15 while the round c101 i have has those 2 wires. and as i asked would i be able to run the car without the oil level sensor wired in since mine doesnt work anyway adn the light is always on.

The engine won't care if the level sensor isn't hooked up.

BTW: the right way to do this would have been to get the round body side of C101 from a 325i/is/ic and replace the square one in the car. That allows you to easily replace the engine harness if it fails.

i have both cuz my harness didnt come with the part of the harness that went into the fusebox

and ive researched this enough to know what i need and im not dumb enough to cut the end of the new harness to wire into my stock harness im not tryin to butcher my original harness or the new harness
im making an adapter from the square engine side harness not the fuse box side and the round fuse box side of the harness per what that square to round c101 diagram shows.

this diagram is what i used to mock it up

Gotcha.

as long as i can live without that causing any issues all i need now is the harmonic balancer waterpump pulley and throttle body then i can do the head/harness swap

Not knowing much about the square connector- is it missing the POSITIONS for the
sender, or just the pins? 'cause you can rob pins out of a similar connector
to populate the empty holes. That's how I converted my eta harness to talk to the i engine...
