This has me curious. You ordered a wiring harness for a K0-K2 CT70 per the part number you gave from Dratv's site. These harnesses have a 4 lug connector. I have one here in front of me.
267R
$33.33
<---- 4 lug connector.
The K3-K6 wiring harnesses also have a 4 lug connector at the motor if I'm not mistaken. Please take a picture of your 5 post connector that was on your bike that would plug into the stock 6V original coils/stator assembly.
I'm at a loss as to where a stock CT70 harness has a 5 blade connector or I'm off base on what you are talking about.
