Hey guys, I pretty much ripped my steering column apart yesterday looking for a good 12 volt ignition lead for an Autometer Cobalt Wideband on my 89 MKIII. Any ideas for me without tearing the center console apart and jimmy riggin it off the back of the stereo? And it mentions something about needing to be plugged into the WOT switch?!?! :3d_frown: I don't even see a way to without tearing the Throttle assembly apart, and I'll be darned if I'm gonna do that!

Any help or experience with these would be most appreciative guys!

I'm vaguely familiar with this vehicle since I only purchased it about threee weeks ago. I know my old 1986 626 turbo had a bitch of a time getting the center console off and I ended up breaking pieces off. Is this one pretty simple? They're both pretty advanced cars for their time...

I used an "add-a-circuit" fuse tap to tap into the drivers kick panel. I believe I used the gauge/cluster fuse. This way you don't have to cut any stock wiring and you can also fuse the new circuit independently.

http://www.autometer.com/productPDF/1143A.pdf is the address for installation procedures.

As for running individual "add-a-circuit", I've never heard of that. Can you uplink a diagram of what you're talkin about and where I can find the tap? It still runs off the igntion power correct, and is not a full time 12 volt?

Correct, it only sees 12 volts with the ignition in the "ON" position. I previously powered my wideband from the radio harness, but quickly realized that circuit's power is cut while cranking.

This is what the add-a-circuit looks like:

The black connector will plug into your fuse box, and you will put the original fuse plus a 5 amp fuse in the body for the new circuit the wideband will run on. I tapped into fuse #1 (GAUGE):

No problem...glad I could help.

The WOT switch is optional according to the install instructions. We don't have a switch in the pedal assembly, and to my knowledge the TPS doesn't have contacts for WOT (for idle yes). I would just directly ground that wire.

Wow, I never thought I would live to see the day I taught IJ. something! Usually it's the other way around. :p
