Lookin' good.

May I ask why you feel the need to run the fuel pump without the ECU powered? Can't say I've found that need yet, I just run the "test mode" in the ECU to run only the fuel pump, if I needed to.

2 reasons, first is the test application which I do not think my ECU doesnt offer, second is that I wanted to have the 3rd button.. :bigsmile: Vain I know, but I think it looks better and if I never use it, no worries.

Spent about 7 hours on the car today, got a lot of the wiring sorted out. I was able to get the switch panel put together with the road lamp switch. I also installed my trunk switch. For anyone following along or just tuning in, on this car I am trying to make a lot of the things "period correct" so I am using a factory 70-71 Cuda road lamp bezel and a factory trunk switch.

I was able to find a quarter window  :bananasmi so hopefully that will get sorted as well (we will see how the glass is).

I will be putting the dash in the car as one unit.

Great progress. Glad to hear that you found a quarter glass.  Your attention to detail is really paying off. that dash is looking awesome.

Yeah it finally feels like I am making headway. I will be the first to say that this car is far from perfect, I have tried hard to make it nice but I have also conscientiously made decisions to leave things alone that were not perfect but at the same time unseen or unimportant. I am definitely not anal retentive but on this project I have had to force myself to be patient and methodical in most cases. Looking back, I could have slammed this car together in significantly less time but I wanted to do things I had never done before like start from a bare shell, design and build a triangulated 4 link, build a big brake system, etc.

The light at the end of the tunnel is flickering; I just might get this car done yet. Then the real issues will begin trying to sort out all the bugs that are sure to be present.

You'll get there. I throttled back on a couple of things in order to keep pushing forward on the car. Stick with it! :working:

Thanks, I am trying. One of my larger issues is that 99% of the time I am alone so some tasks are pretty difficult or I have to find help. Once I get the dash in, I can run and terminate the wiring. I will need help getting it in along with putting the windshield and back window in; but other than that I can do the rest by myself I think.

Anyone know how much amperage the starter (ignition) switch draws during starting?

The starter current, or the load through the ign switch during cranking?

Not much is powered while in crank, the coil  and starter relay. Just a few amps.

Well my system instructions are saying if I draw more than 10 I need a relay.

I would pass on that, I don't think it'll be above 10a.  :2cents:

Goody,

A buddy of mine and fellow member here (Crash340) did some testing for me and here is his results, you might find it interesting.

I have the following wires coming from my battery
 
1) Starter cable(heavy)
2) Power to the amp meter so it's also connected to the black wire which used to come from the alternator but now stops at the bulkhead connector, so this red wire from the battery via the starter solenoid and through the fusible link provides all constant and switched power to the ignition switch, lights, dash etc.
3) Constant power directly to the EFI ECU
4) Constant power directly to the CDI
5) heavy cable to the alternator
6) fuel pump supply (draws 15A running)

Current to the switch
   The ignition switched to acc, wire 2 draws 5.9A
   During start (cranking) it draws 15A
   After start engine running it draws 4A

During running the EFI ECU draws 1.2A (wire 3)
During running the CDI draws 2.5A (wire 4)


I am going to install a relay to be safe.
