Making my own tuning harness ?
Yeah I'm using a length of wiring harness from an obd1 accord and I'm just going to desolder and reconnect the right the cut end to ecu plugs I'm desoldering from an old ecu. But anyway I want to power my Lm-1 from the harness so all I have to do is install the sensor plug into the cars ecu and harness and go.
What Pinouts would be good for powering the wideband looking at it I'm thinking of going with D1 for power and D22 for ground. Would that be ok or is their a better way?

Re: Making my own tuning harness ?
i have a writeup on installing the lc-1. i have obd2 and obd1 pinouts on it.

but go look at pgmfi.org. they guys over there have some threads on their "ultra portable" ecu/wideband tuning combo's. they can almost pretty much just plug and play into cars to tune

Re: Making my own tuning harness ?
I made a custom harness for my plx m300.
I used an spare extension cord I had laying around. Used that for the + and -. Then extended the signal(white) and ground to reach the o2 sensor plug. I took an old o2 sensor with the harness and cut it right at the plug. Then I used that to connect my wb to the car. The signal goes on the white wire(it goes straight to the ecu, d14). And then also used the ground and power from there.
I'll have to take a picture of it. It looks ghetto as ---- but it works.
