RK56 wiring

[the caveman]

Hello junkies today I'm working on my Telex Turner RK-56. I'm having troubles figuring out the wiring. Mine seems to have different wiring compared to the ones I see online. I'm deciding on whether im going to wire it to a 5 pin for my cobra 19 plus or to a 4 pin cobra 25. Here's some pics guys (sorry the tablet only has a front camera)
