Identify Power Antenna wires

[shazam]

I'm replacing my original power antenna with an after market power unit. The original unit has 8 wires (including ground)....the new has 6. I have Haynes' Repair Manual....which is useless. Anyone have a wiring diagram...or, reference link I can go to, to identify those wires?
Thanks, in advance.

It may help to identify what year Miata you have. It's not in your profile either.

Also, why are you replacing it?

My Miata is a '93....and I'm replacing it because the plastic drive cable has broken. I purchased an 'after market' unit for a good price (good move???). The "after market" unit has only 2 wires (besides the ground & antenna leas): Red (hot) and Blue ("antenna trigger wire"). The OEM has 4 wires: Green/ B stripe; Blue/W stripe; Blue/Y stripe; and Black/Y stripe). The "after market' guys have not responded to my pleas for help! Maybe I should just return it and fix my old unit??? PS I've updated my personal profile.

FYI: You can get a replacement drive cable for $21.63 from Trussville
