Post nr. 125	The 1.3 harness is installed and I've a few questions. I can't get spark but it may be due to some simple items. The main question I have is what is the minimum needed to produce spark. The crank sensor has to be hooked up but how 'bout the injector rail? ICV? TPS? Does the ECU have to be installed and grounded? It's sitting on the floor right now. Anyone got some advice? edit** OK, I think the harness was mis-labled by the individual I got it from. In particular are the wires exiting the harness as it goes through the firewall. I peeled the casings back to determine everything was correct and I think there's a problem. There's several red wires which obviously go to power supply. There's also one bundle of brown and one of brown/orange. I'm assuming these go to ground. Brown/orange was labled as positive but this cannot be correct. I can only hope nothing got fried!
