power logger Question map install

[robzombie]

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 signal.

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.

Traced them under the dash and found it.. Thanks.

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
