Transmission connector

Switch connector???

I am afraid you will have to be a little more specific as to what you are wanting to hook up before anyone can give you accurate information.

If the OP is referring to this unit - Polaris Slingshot Aftermarket Stereo Wiring Harness with OEM Backup Camera Integration, it is designed for 2017 and earlier Slingshots and should allow him to hook up the rear camera to his Pioneer radio if using a 2017 or earlier Slingshot. The faceplate/dash opening on the 2018 is different to accommodate the new, larger display for the Rid Nav system. This thread is about one individual's attempts to install a radio in his 2018 base Slingshot - 2018 model s Radio | Polaris Slingshot Forum.

Im pretty sure he what he wants to know is how to get his hand down to the connector to put the reverse wire pass thru on.

I couldn't do it with the dash on. I think the only way is to remove the dash top and you MAY be able to get to it.

But even then its tight to get to. And dont think its going to be easier underneath... it's way up there in the tunnel.

I never did get my hand down to it. So I just wired mine to a switch and I did @larry the same way.

And it it really cool to watch behind you riding down the road by a flip of a switch.

I ended up just using the camera connector. I tossed the whole relay harness on the counter and didn't use it. I had already cut the power plugs off so I didn't need them.
