So you guys think the treehouse wiring adapter is clean?

[FredK]

^ Yep. I was able to get the other pins for the larger wires from Tischer (193 and 195).

[Jason89i]

dont forget, there are different pin #'s for 3 different wire sizes. buy the right pin for the corresponding wire size.

ive done this on a couple swaps. definately the cleanest way of doing it.

ps, dont forget to buy a wire crimp. using needle nose pliers can lead to a loose wire in the pin.


cheers, jason

Dang. I ordered from Tischer BMW and they did not allow me to order the pins under the 191 part number. I paid $0.53 at Newark. Realoem says nothing about the 191 PN being superseded by the 452 PN either. ARGH.

[matt]

Blast from the past. I'm glad I quit patting myself on the back like this.

PS. You were lied to by your parts guys... Those part numbers don't supersede each other at all. In fact, there are 253 of the 191s in two of BMWs warehouses. List is $.53 each. In fact, there are about 20 of them sitting on my bench at work...

[FredK]

and the male pins are 05 CIRCULAR CONNECTOR D=2,5/0,5-1,5 ? 61131376191

For some reason, when I ordered 61131376191, I was told it was superseded by 61130007452, which is the same pin but with flying leads attached.

So, I ordered AMP 929967-1 which the equivalent AMP part number. Geometrically it's the same as the BMW pin, though I am not sure of what the BMW pins are made of or the plating material. The AMP piece is CuNiSi with tin plating.

Normally, at Newark, it's a non-stock item, but it just so happens they still have like 2700 pieces left.

I have access to an AMP crimp tool, so hopefully I can clean up my embarassingly messy wiring harness up this week. :mrgreen:

Yup. I'm freaking crazy like that.

I did the same as Rev Engineer, but the best way to do it is as the thread starter suggested-- although I would modify the e30 side as to keep the engine harness intact.

I'm going to get the parts to do this eventually, too.

You'd modify the car side, which has wires running through the whole car's wiring harness and would be impossible to replace vs the engine harness you can get for $100 all day long? :loco:

^^ looks clean

[Rev Engineer]

Here's a couple pics of mine. I was really tempted to make a nice short harness and either cut the s50 or e30 connector, but I've decided that I might go back to the s14 engine and sell the s50 after awhile, so I made an in-line connector. One end fits nicely into the stock location and the other fits nicely into the diagnostic holder. Looks pretty stock except for the relocated diagnostic connector.

Wow matt....u have read my mind!

I was thinking how neat the job would look with an E30 M3/ 4 cylind wire harness fixings (the plastic bit on the firewall on E30 M3s ull see all the time!) and yeah began to think of reconfiguring the existing c101 to an E36 female plug to mate to the standard E36 engine plug....ur a champ! i want to see pics mate!
It would look factory and soooo tidy. Its a shame the tools cost sooo much..
but its worth further investigation...
You could then use the factory mounting point on the firewall too...nice i want to see pics matt please!!!

As for the TreeHouse bashing...guys try living out of the US when the xchange rates arent in ur favour!!!! lol i like treehouse they are E30M/S50 friends! that plug is gold to us!....but this thread was more about true OEM fitment.

Matt did i mention i wanted to see pics!!!

Chicken scratch is relative. $400 to me is a lot. I don't consider the treehouse adapter a bargain, but maybe that because I'm an ee and wiring is easy for me as long there's a schematic to follow. I think there's enough wiring info posted on these forums and enough schematics readily available that making an adapter should be relatively painless for most people with a little electrical knowledge. And, there are people on these forums willing to help people who are having problems. Of course there is the time factor as making an adapter takes time to research and to make, and maybe that makes up for the $400 cost to many people. But for people who are working with tight budgets and also enjoy doing some dirty work themselves, should benefit from savings 400 bucks and doing this themselves. Maybe if another vendor comes out with the same products and offers good customer service, treehouse could see some competition and lower their price. Personally I think asking 400 is a slight disservice to those of us who struggle to come up with the mega bucks required to do these projects. The r&d that treehouse has in the connector (which probably accounts for a large percentage of the product cost) is losing it’s value as more wiring diagrams and conversion wiring details become public knowledge.

[matt]

It is on it's way. ;-)

It showed up today... I'll have the pins on the e36 harness tomorrow, then I'll take your old connector to work Tuesday and punch the sockets out... then it's done! :buttrock

[BDSax]

oh guess i misunderstood.

[redhatpat]

$400 is chicken scratch when you can put an m50 in your car, and have it run, without having to put an ounce of thought into the wiring.

Well, maybe not chicken scratch. But definitely a fair price for a good product.
