Head unit wire extender

makeao

I have NiftyCity one.

Already did my research and ordered 3 Metra harnesses: Metra 70-7553, Metra 70-7552 and Metra 71-7552 for the male one.

I ordered 3 because the metra 70-7553 lacks 3 pins that I will need in order to get everything working, so I will take the 3 extra pins from the 70-7552.

Checked AV manual and made a diagram, also checked that diagram with my car and it matches. So once the harnesses arrives it should be pretty straightforward.

Here is the diagram I made in case someone is interested:


By this approach you can wire as u want without cutting any OEM harness on your car.

I'll post more pics and results when everything arrives (It will delay a bit since Im ordering to USA from Spain).

My only concern now is what is "shield" wire doing, and if I can extend that one aswell as a normal wire or just omit it.
