'70 Dart 392 Project; what direction?

That's good to hear cause that's what I came up with. I ordered these connectors from Ballenger as I hope they're going to match up to the coil plugs.

Cam/Crank sensors I ordered these:

TPS/IAC/IAT/Coolant Temp/injector connectors I ordered from the DIY Autotune website. Should be fairly straight forward on those.

MAP sensor I was planning a vacuum line but I do like the idea of not running a line through the firewall.

I also bought one of the DIY autotune bulkhead connectors. Should make it a little more clean.

Plan is to mount the ECU in the glovebox as my underdash stuff is pretty packed already. Should be an easy shot through the firewall through the bulkhead connector.

Only thing I'm wondering now is identifying signal/power/ground terminals on all the sensors.......

Nice! I didn't know Ballenger had those. I've purchased from them in the past. They have a nice selection of things that would otherwise be hard to find. I think I was able to find the crank and cam pinouts online by searching. If you don't already have them, you will need ignitors for your coils. DIY has them. THey call the quad spark modules. DIY also has a wiring bundle, which makes building the harness super easy.

My ECU is in the glovebox as well. I used the Deutsch bulkhead connector. You can see it on the center of the firewall.

If this is your first time messing with EFI, I can't stress enough how important grounds are. Notice I have grounds on each head. I have a ground connecting the heads and block together. Then the engine block is grounded to the frame rail. The battery also has a cable to the framerail, along with a ground wire running under the dash to the column support bracket. All ECU grounds are connected to that point. If you think you have enough, add more! I obsessed over it and guess what, zero problems with noise or crazy ground loops.
