I have everything else connected proper.. im pretty sure. The purple and green wire, is the power to the fuel pump.. it turns on momentarily when switched on. So ive spliced I to that.. but im stuck as to knowing where to connect the splice to.

you could use a PWM module off a junkyard E46 and do the same thing. pretty sure you could score one for $25 or less.
it's got power, grounds, and the PWM signal. MS2/3 has enough PWM outputs to control that no problem.Comment

I'm struggling with the install of my LC-2. There is only a single ground for the LC-2 so the wiring doesn't really match what is here.
I cannibalized a stock O2 sensor harness and spliced the LC-2 into the other half of the original O2 sensor. I popped open the relay as shown in the first post and shorted it. Everything seems to work fine. The engine runs and settles in at stoich after it gets up to temperature, but I am getting a stomp code and hesitation (I think the hesitation is a different issue).

Did I wire this up incorrectly?

Is there any way to tell if I damaged it without cannibalizing another relay? I do have a spare(s?).
Maybe the solder connection inside is bad. I seem to remember it struggling to take hold on one of the surfaces when I did it, but I thought it eventually took.Comment

Try jumping it with external wiring on the forks instead on your spare relay and see if the CEL goes away. A code is a code and it's directly pointing to the relay and/or wiring so give it a shot!Comment

I am about to switch over to a megasquirt unit. Any tips on where I should ground it? Is the shocktower okay for megasquirt?1987 325is 2.8L Stroker Turbo "Little Pickle aka The Green Turbo Sled"Comment

Considering putting a normal O2 sensor back in for now...Comment
