[W126 Coupe] Gearbox wiring help really, really needed please!

[Satish Tummala]

Ok, here goes...

1.  The fifth wire is for the first gear start module that is activated
when the neutral safety switch gear position "3" or "2".  Therefore,
transfer over the neutral safety switch from your 500 transmission to the
560.

2.  The two pole connector probably goes to the overload switch on the
side of the transmission of the 560.  This harness has two poles, one to
ground and the goes to the EZL ignition control unit.  It retards ignition
timing for 400 milliseconds or so at redline for a faster shift when
driving spiritedly.  Therefore, transfer over that switch from your 560
box.

See ya,

Satish
