Another Mopar Off My Bucket List - Barracuda Fastback

We managed to pull the MSD box off of the Roadrunner without too much effort. It gets confusing when you're dealing with wiring instructions from FAST combined with wiring instructions from MSD. There are no schematics that show the two combined and the MSD needs to be wired differently than it's instructions show in order to interface with the FAST controller's firing signal. I made certain to draw my own schematic before unwiring the old box.

Next it was time to turn the Barracuda into a parts car. I had all the wiring bundled tightly and wrapped with electrical tape, plastic wire conduit, and pull ties. Oh well...

It took a few hours to make the swap. We could have done it much faster but we took the time to route all the wires neatly. The FAST system hates electrical noise. We had all of the wiring finished except for the few connections we needed to break for testing the MSD box. - Then we performed the test again.

SUCCESS!!!

The rain came back just after we'd finished our test so we had to stop again. Although we hadn't been taxing the battery much I decided to disconnect everything and put the charger back on it. According to my battery charger it was down to a 52% charge. This battery isn't going to cut it. We may get by for now but we need a replacement.
