He did this four months after the new battery was in (when it started having problems, he called Greentec).

PS I think I fixed the pics let me know if they are still broken. (I can see them).
I can see them. I'll check my HCH1 harness when I get home and let you know.

So, it looks like 2 things are needed to get that pack working... potentially fix the splice job and install a 20 Ohm resistor.

BTW, this harness is for monitoring the 3 thermistors and the PTC strips. Simplistically stated, the PTC strips are basically a resistor that runs along the length of each stick with with a probe on each cell. If even a single cell gets dangerously warm, the strip resistance goes very high. The 20 PTC strips are connected in series between the red and blue/yellow leads. A 20 Ohm signal tells the BCM that there is no catastrophic cell heating going on. With that signal steady, the BCM operates normally based on the 3 thermistors.

No aftermarket packs contain PTC strips. Honda discontinued them on the HCH1 sometime in 04. They haven't been on an HCH2, G2 Insight, CR-Z or Accord Hybrid. However, you may the ECU that expects them.
