I just installed my power logger and was wondering if anyone knows which wire on an alky control unit [under dash] could be used for the l2 on the I/O of the power logger so I don't have to run a wire to the actual map sensor.


I'm assuming the aux map sensor is for a dedicated W/B setup, which I will install next week.
 
Have you seen this?

MAP Connection:

This is what I used. I took me some time to understand all the connections but it worked like a charm.
The second step with the grey wiring may not be needed but I tried it without doing it then with doing it and it did make a slight amount of difference in the readings.

Green wire is the map signa

I know that off the map it's the green wire, just looking to do it from under the dash instead of running more wires through the firewall.

I'm not sure I understand. Just put both the green MAP wire and the green AlkyControl wire in the I2 block. No need to run any additional wiring into through the firewall.

Why would I need both green wires???

The one coming off the alky control should suffice, as far as I can tell they both would carry the same signal/voltage.

If I'm wrong please explain why I need the wires from the map and alky control hooked to l2.

I want to have accurate readings and if there is a reason for both please explain.

Thanks RZ
