5.9 swap in 71 dart
I'm using the hot wires engine harness. I put in a push button starter to have continous 12v to computer. I'll make sure of that tonight.
In that case just use the original ignition switch with both Start 1 & Start 2 connected. you wont need the push button start anymore.
The reason they used Start 1 & Start 2 in the first place was to bypass the ballast resistor , which induces a voltage drop. Bypassing it with Start 2 gives a full 12 volts to the ignition for easier starting, especially when hot.
I found an open ground on my oxygen sensor circuit, so the car went into limp mode after the 30 second O2 sensor warm-up time. Once I grounded it, it ran great.
I did use the fuel pump relay circuit to control my fuel pump, because it runs the fuel pump for a few seconds when the key is turned on to help starting.
A buddy who used to be a Matco Tool salsesman let me borrow his scanner. I would have been lost without it. I believe they make a system that uses your smart phone and a wifi OBD2 port plug in to do a much deeper scan function than the cheap over the counter scanners that are available. If so, it would bridge the gap between the cheap scanners and the $1k+ units like I had access to.
