no seat memory after 5spd swap
#17
I have looked at this exact diagram before and never even noticed the two different locations for the ECU. In my other thread, everyone was convinced it was up there near the clutch pedal. DOH Thanks so much for "making" me revisit this You do have to remove the glove box, and the structural lower dash bar, then it's in plain sight, mine was green though, not white. I found the gray wire at B6, made a little jumper and grounded it under a nearby screw and voila the seat memory works !! This is great news, even though I'm the only driver, LOL.

You grounded it and now it works? Cool. I wonder why it broke in the first place since you are a factory 5 speed. I had to give mine 12v.
It's funny that you mention you have seen that pic before. I actually almost posted that pic with the location under the steering wheel circled, and while editing the picture, the other location caught my eye. I had never noticed it before either - and I have looked at it over and over as well!

yep, pretty easy really, but I was so frustrated months ago when I was determined to fix it and couldn't even find the damn ECU LOL.
Exactly ! I was thinking the same thing.

what is the cure for an auto without cruise or memory seats? my CRUISE light comes on when i push the button but i do not stay at a constant speed ive tried all the options on the cruise control stalk. my memory seats do not work either and it is plugged in. does neone have the wiring diagram for this?

To make the memory seats work, you need to cut the gray wire on pin B6 of the Tilt\Telescopic ECU under the dash to the left of the steering wheel. Run 12v from a switched power source to the ECU side of the cut wire.
To get cruise working again, snip the black and white wire on pin 2 of the cruise ECU above the brake pedal. If you want the clutch to cancel the cruise, you'll need to wire it up the switch on the clutch pedal.

I've been under the assumption that my seat memory not working is due to a dead telescoping wheel motor, but now I'm wondering if it's just a bad signal to the seat memory ECU.
I'm confused by the conflicting instructions of grounding B6 or adding switched 12V power. Does B6 normally receive power and the problem is that wire gets damaged and loses its signal? Or is B6 normally a ground and providing power overcomes some other problem?

Haha, I didn't expect you to be the one to respond all this time later. I was posing the question for anyone who happened to read it and have some idea.
Mine is an unswapped A/T, by the way, so there's no real reason to think it's something directly related to this thread's topic. I'm more curious if something there could have gone wrong that's worth testing the B6 wiring.
