Hooking up LC-1 WB. Cleanest way?
What's the cleanest way to interface an LC-1 to my ECU? I know this is HMT and a lot of you guys might just say to use wire nuts or some ----. But I don't like doing ---- that way.
I was thinking something modular like hooking up a connector to my conversion harness. Does anyone know where to source some nice honda looking male/female connectors.
Also, does anyone know if the ECU power line can handle enough extra current to power the LC-1. Or do I have to get a dedicated 12v for it?

I tried using an old wiring harness connector but I didn't have enough voltage!
But once I connected it good, my brand new LC-1 was giving more trouble codes, so I'm not sure if that was my only problem!

i used the plugs from my old power mirrors on my teg and soldered them into a 0bd 1 to obd 1 extension harness. that way i can plug and un plug it when i need to tune some one elses car. also, because i used the extension harness, i dont have cut any wires on the cutomers car

I tried doing a plug-n-play on my Escort. Stock sensor is 4-wire (12v heat, ground heat, signal, and signal ground). Figured the heater wires would power the LC-1 cable. It would keep on resetting and giving error codes and throwing itself into calibration mode while driving 
Rewired the power through a 10A fuse labelled "rear wiper" (sedan hahaha), and the ground to body. Works 100% now. Power supply for the stock sensor just wouldn't push the amps needed.
If this helps you avoid a stupid problem then great, if not just consider yourself .01% smarter

I wouldn't suggest the Cigarette lighter. Many Manufactures advice you against it as it is no a stable enough power supply. I tryed it once and the widebandgave an error stating the was not enough voltage.
