Ebike 4 pin adapter plug

This is totally a weird sketchy work in progress. Designed for a Huffy ampt st that has a 4 pin out on the battery sled. Basically i'm working to adapt the 4 pin out on the battery sled using a 3D printer block, some spade connectors and wire to an XT90 connector so I can connect a larger battery in a frame bag without ripping up the factory sled so I can easily swap in the factory battery when ever I want. Basically building an adapter cable. The pin spacing is probably similar to a lot of low cost ebikes so you're welcome to have a go. PLEASE DON'T GET YOUR POLARITIES MIXED UP AND CAUSE A FIRE. You've been warned so it's totally on you. This is sketchy, DIY and 100% play at your own risk kinda stuff. If you get electrocuted........ I warned you. Safety 3rd

I've uploaded a few revisions I've gone through. This is my first ground up model so you don't need to tell me it's a little crude but it does the job.
