Reverse Won't Engage - 2003 RMK 700

So I took my 2003 RMK 700 out for its first ride after having the steering and engine out. Everything worked well, but reserve. When I push the reverse button, nothing happens.

I am sure it is just a electrical connector that I didn't get back on tight.

I checked all the ones I could readily see and pushed some together tighter, but still no luck.

Can anybody direct me to which colored wire and which connector blocks I should concentrate on?

Thanks

I saw those and they looked good, but I will go take another look and inspect them a little closer.

Thanks.
