THE E36 328TI IS ALIVE! | E36 Wiring Harness Walkthrough 

So turns out that harness with the "Y" split you're talking about was not originally part of the engine harness at all. Those connectors were added later when a recall was put out for faulty crankshaft position sensors. My guess is that the car that my engine came out of wasn't affected by the recall and therefore did not need the subharness. Thanks for pointing that out though because I imagine that will be a point of confusion for some people using my videos as a "how to".

Hell yeah man! Good luck!

I be coming back to my videos every once in a while when I forget how to do something 😂

Ayyye good stuff! Hope it goes smooth!

Thanks man I appreciate the kind words! If you're looking for a good shifter I would look into the PMC chassis mounted short shifter. I've been running it for a while and it's super nice for the price.

How’d you get it to run without res delete

In my case I had the key “chip”, DME and matching EWS module from the donor car.

@@toddkane3152 is that more complicated. Because I’m planing on getting a parts car with an m52 mm

Thank you!

I'll hopefully have me an e36 or e46 by the end of this summer just gotta grind out work

@@xx_jason_xx5568 Hell yeah man! They are super solid cars if you know how to work on them and keep them in good shape.

Hey man sorry for the late reply! To my understanding a pre 1998 e39 m52 wiring harness will work. In 1998 they moved to the dual vanos m52 which won’t work with the single vanos m52

They were for the secondary air pump system and the evap purge valve, both of which were deleted.

@@JamDrifts thanks man

From my limited research it seems like it should be just as plug and play on the z3. Of course you’ll need to take into account which OBD version you’ll be running based on the year of your z3 but the process should be nearly identical to the swap on the 318ti.

Wiring harness is out of the automatic 325i and needs to go into the Manuel 316i

You’ll need to do some wiring to get the reverse lights working. I don’t know the specifics since I didn’t feel like doing it on my swap but there is plenty of info on the forums about it. If you’re using the ecu that came out of the automatic it’ll search for the transmission control module so you’d need that hooked up too. Since my ecu and harness came out of an automatic too I ended up just getting the ecu tuned as if it came out of a manual so it wouldn’t need the transmission control module. Along with that you’ll need to have the EWS immobilizer system tuned out depending on the year of 325 it came out of.

^harness as well

The fuse box is the same as the 4 cylinder but you’ll need the engine harness for your specific engine.

It's a 98' so it's and obd2 engine and chassis.

@@JamDrifts wait so all you needed was the ews delete ecu? You didn’t do any wiring to ews module
