Looking to upgrade my current E6K setup to a 1500. The E6K was already installed in the car before I bought it and I have some concerns. Mainly how it is wired into the rest of the car and how to properly replace it with the 1500. It doesn't appear to have been talked about much and looking for advice on steps where to begin.

 

basically you can re use the sensors, but ecu and harness go in the bin. going from an E6K to, well anything else is a huge leap forward.

 

Going down this rabbit hole again. Had some life changing events occur (wife got cancer) and car stuff got put on hold. Does anyone have a original wiring diagram of E6K? Trying to figure out what a few wires are going to from the E6K to oem wires. I think I have figured out 2 of them but not 100%. One is a pink (E6K) to black/green stripe (oem) wire in passenger side kick panel and the other is orange (E6K) wire coming from battery to white/red stripe wire (oem) in the driver side kick panel. I believe the black/green is to ignition and the white/red stripe is fuel pump relay. The white/red stripe does go all the way back towards the fuel pump, but looks like it goes beyond the fuel pump.
