I'm 60 and not sure about wiring up a mmc I bought so I'm in need of a little bit of help. Firstly I need a gps cable and don't know where to buy one, seen plenty of 8751A parts but my unit is 8750A so are they compatible? and secondly I'm not sure if this part goes on top or bottom of the unit or the wiring

so I'd be really grateful for any help

to fit this unit

Probably didn't make my self clear, I know where all the plugs go, not senile yet, I have found out where I can buy the cable for the gps antenna. One problem remains, the plug to the gateway unit and where does it go? also have a green plug spare?
