vic,

my wiring project has been delayed, but hope to get the battery to trunk then start the aaw harness in the next couple of weeks. If you could rewind for me here...did you run a ground wire from the trunk up to the engine block or just run a ground in the trunk and a seprate ground from block to frame? Didn't see it, but may have missed it. Build is coming along nicely. Your attention to detail and patience is what i will strive for!

Hey Cav.   If you look back at the pictures I posted over the winter, you can see what I did.   If you need more, let me know.  To summarize:

I grounded the battery locally in the trunk to a support bracket, using a tapped hole and a bolt.  I ran a wire from that to a ground terminal block in the trunk.  The stuff that is mounted in the trunk is grounded to there.   I also had several items that needed to be grounded directly to the battery that were in the front of the car.  So, I ran a ground cable from the rear ground block up to the front of the car, and installed another ground block there.   This is used mostly for electronics, as I have a VHX dash computer, the Vintage Air computer, a digital ignition box, and EFI computer that all should have a solid, separate ground to the battery.    

In the engine compartment, I ground the "power" stuff locally.  I am running my block ground from my starter mounting bolt, directly to the frame.   

Here is my ground block diagram

So, VHX is for my digital dash, VA are my Vintage Air Grounds, P2 is my Pertronix Digital Ignition Box Ground, PWM is for my Pulse Width Modulation Fan Controller, Pwr Amp is for my Rockford Fosgate 400 watt power amp.  The line that runs from the trunk terminal point 4 to the dash terminal point 7 is my "back to front" ground wire.  All my power and ground stuff is routed on the right side of the car, my low level and control stuff is on the left side of the car.

Hope this helps...

Vic

Vic,

thanks! I must have missed how you did the grounding with the busbars earlier in your thread. Great idea and had not thought about doing it that way, but makes sense now. appreciate it!

If I did not have all of these digital boxes, I would have done it differently, but if you don't have a good ground, you will find out the hard way.  

Let me know when you get started in earnest on the AAW harness.  I have lots of lessons learned.  If you know how to use Excel, I can send you my spreadsheet, and then wak you through my approach. But, I mapped every wire on the harness.

With the weather getting nice, moving slow on my '70 project.   Got the trans under the car today.   Once I get it secured, then will drop the front of the car down, and get the engine in.  Memorial Day weekend is looking like the perfect time to do this.  Have to get my '68 cleaned up to take to Carlisle.

I dropped the 302 with a small case c6 into my old 70 all bolted together ,actually easy ,even slipped in headman long tube headers just before the moter seated ,i left the headers loose then tightened when the motor was bolted down . Saved a lot of time ,use a lot of blankets to stop scratches

I have done that before also.  This time, I want to drop my engine in with the serpentine system and headers bolted on, and will need to steer around the Borgeson steering box, and center link, and a fully detailed engine compartment, engine and trans.   So, will do it the hard way.....
