I am working on installing my AEM Wideband Gauge (30-4110) and I finished reading through the following link:
AEM Wideband O2 gauges
I have a 1981 Porsche 911SC
I have a a couple of quick questions to confirm I am doing the correct thing.
According to the above link (post#17) when powering the gauge I run the power to the cig lighter fuse and the ground up to the fuse block.
1) I am not sure where to ground the wire to the fuse block - so would just grounding it to the body here (where I circled to the left) work?
2) Also - when running the red (hot) wire to the fuse - do I just screw it into the top of the cig fuse (circled in the middle of the pic)? Thats it?
NEXT QUESTION
According to the above link (post #37 and #51), I can (if I so choose) run the white wire and attach it to the wire that feeds the Lambda system (the green wire that used to plug into the o2 sensor) AS LONG AS I ADJUST THE AEM gauge TO THE CORRECT POSITION...
3) Is this the o2 wire that runs into the Lambda DME under the passenger seat? I hook the white wire to this? (sorry if this seems obvious - but my o2 was not hooked up)
