Icehouse 1,854 Posted December 20, 2020 Author Report Share Posted December 20, 2020 Where is your keyed power hooked to the car? I would unhook it where it hooks to the 510 harness and see if it shuts off when you do that. If it does something in the original harness is keeping it on. Great looking wiring!!! Quote Link to post

Thanks for replying Jeff, the Key Pwr is the 12ga blue/red stripe which is taking power from the black/white wire that use to go to the old coil. I just disconnected it and the ECCS and Fuel pump continue to run so I guess I should check the #46 & #109 ECU Bup next? I just edited the 1st post, all 3 circuits come on with the ignition key, turn the key off and only the RUN circuit turns off, ECCS and Fuel pump remain on until the battery is disconnected.

Hmm that is an odd one. Something is back feeding but everything looks correct. My only guess is there is 1 black with white stripe wire that comes out of the ecu that does not need to be hooked up to the others. I think it's for powering a component we don't use. That wire could be back feeding the system and not allowing the ecu to shut down. keep us posted Quote Link to post
grannyknot 159 Posted December 21, 2020 Report Share Posted December 21, 2020 You were right, #47 black/white. All the lights and the fuel pump turn off with the key, Thanks. I was wondering if was possible to hook up the OBD 1 wires so I could read the codes? Quote Link to post

Mxvxc 0 Posted February 5 Report Share Posted February 5 Ok, stupid question about to be asked, and yes I’ve already poured over the 42 pages of this forum numerous times before I gave up and decided to ask for help. Single cam KA into ‘69 goon. Question is regarding the ECCS portion of the CAN/AM box. I’ve stripped the engine harness and tagged all of the required wiring to run into the box, however, the black w/ white stripe wires are my problem so far. Wire 109 is easy to chase and ends at at a unused plug, BUT, my 38/47 black w/ white stripe wires are actually tied back together about halfway down the harness and end at the plug that attaches to the MAF sensor? So what do I do with those two wires? I can’t imagine I’m supposed to cut it from the MAF sensor plug, or do I only tie wire 109 into the eccs block?? Appreciate the help, I might have been a little too ambitious as I’ve never done an FI swap and am on my own as far this build and don’t know of any local vehicles, that I’m aware of, to just physically go look at their setups.

All the black with white stripe wires hook together and connect into eccs1 . If you just connect from chassis plug you don't need to trace them all out. There is just one black with white stripe wire at the chassis plug. Quote Link to post

Just always try to remember to “measure twice, cut once” kinda thing. Quote Link to post
