WTB: ECM connectors(car side) + ECM male connector(ECM side)

[CTScott]

The female side comes off of an engine harness and the male side comes off of an ECM.

ECMs can be purchased for as little as $25 if you hit them right on eBay or at a junkyard (I have never paid more than $50 for an ECM {and, yes I have bought about half a dozen over time for various experiments}).

Harnesses are trickier. There are two separate engine harnesses (terminating to each of the two ECM connectors). I caught one set off eBay for $80 each, but typically people ask $150 to $300 each for them. I bought one of the large connectors (the smaller one was already gone) from a junkyard that let me harvest it myself for $20.

There is actually a ton of labor in making the harness, since there are 36 connections on connector A21 and 63 on Connector C20. The AEM F/IC only makes a total of 23 connections to the harness, so to make a plug and play harness you solder 198 connections (63+63+36+36) to make the Male to Female "extension cable" and then 23 to then connect the F/IC to it.

So, after working with Adrian's Boomslang, I would say that the plug and play is nice, but is an incredible amount of labor in comparison to making 23 connections.

As for the colorblind piece; I never trust wire colors, but rather always follow pin position.




Edit: Actually 99, not 198 as long as you harvest the female side with enough wire still attached...

Oh, just 99?


In that case....


I didn't think about using the pin location vs wire color, is there a diagram somewhere that I can use to determine what's what? If it saves that much work and money, and I can do it myself without having to guess it's probably the best route...it would speed up my install considerably.


On the other hand I did find the components I need locally, if I had an idea of the labor cost I could more readily determine which direction I should take. Hopefully a wise and powerful electronic wizard will send me a PM with an estimate.
