Another E30 M30 Swap Thread, this time with an 84 318i

[Mr. Burns]

This harness came off of a running m30b35 swap on the same motor... its an extended m20 harness though.

Hmm interesting though..

Can you clarify this please?

it is an m20b25 harness but pre-spliced to work with a b35?

The harness has been Extended in certain areas like spark plug wire and other necessary extensions. The harness came off a late model e30 with m30 swap, so there wasn't a need a to splice in a switched 12v source.

But now that I've swapped everything out of the late model into an early model, I've had to splice in the ignition wire from the c104 for switched power and can confirm I get voltage.

I also spliced in a constant 12v source to pin 18 of the dme plug as stated in the original post.. this splice is done after the main Relay, between the relay and dme. To clarify this means my dme is not receiving the 12V from the main relay like it would usually, but since I T spliced a power source to the wire, power should run up and down the whole line.

Can you clarify this please?

On the battery still at 12.22 I am only getting a readout out of dme pin 27 of around 8.03 hmm. thats out of the ignition wire from under the glove box..

wow just checking right now, I just bought a new main relay, Now the green ignition wire coming from the glove box, AND just the green wire itself have power? To add to the confusion, when I put the new relay in, it turns my car into the "on" position and my dash board lights up. Only when removing the main relay does it shut down completely.

Needless to say, getting a constant out Green wire 27 AND the Ignition wire under the dash.

Main relay lights everything up until pulled, That being said When I insert the relay, I hear the unloader relay (K7) gate engage. hmmm.


additionally I will take pictures of a 3 prong connector, white in color with a green/purple, red/blue, and Brown ground wire going from the dme to this 3 prong connector about 6 inches up the harness.

Any updates? Great thread too btw.

It's been raining quite hard the past few days, so ive been focusing on other items.

I think I've solved all my leaks around the firewall and found out the channels leading to the drains were packed with pine needles which was causing water to seep between the blower motor seal and the firewall itself.

Took out the stock antenna and plugged the hole. I also installed the euro grills and black kidney grills, and now I almost want black trim, the Delphin metallic and black looks nice to me, but my wheels are silver, and I'm not very convinced with painting the diving boards, but perhaps in combination with a minor tuck it would look okay.

Currently I'm laying down some cheap frost king for minor dampening and insulation purposes, then in with the new carpet. The frostking is very user friendly, and I personally feel it will do a great job.

Glad to see an update. Been wondering how you're doing. Probably starting to get cold up there, hope you have a heater...

[the imitator]

sigh... ive been so busy with life. I've been making myself satisfied by doing small projects to the e30 before I leave in the early December.

[G-Man the Visionary]

So close, yet so far. You've got a ton invested in this beast, git r dun! Si se puede!

[the imitator]

Well I have a bit of an update.

Do to the massive amount of rain in California we are being called down for work. We are leaving Wednesday which means I needed to find a place to store my car.

Not only was I offered a place to store it, these fellas who have kindly offered such space have also offered to also finish the swap for me!

sa yall can go home now..

[Mr. Burns]

What in the what?! Who are these angels fallen from heaven?

[marshallnoise]

I hope you trust their work.

[the imitator]

Haha, i said something along those lines too! These fellas have 4 e30s and just finished their 3rd m50 swap and one gentlemen in particular has an e30 M30 project he's boosting. I throughly believe these guys know what's going on with no doubt. None of them are forums members or show goers, just a few guys that dig the e30 platform.
