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

[Sharan Bains]

Since you are using the 500 ignition and fuel systems, the early 500 EZL 
won't have that functionality for the transmission quickshift will it?

Also, you'll have a hole on the bell housing for the CPS - may need to block 
that off as the early 500 ignition system does not have that there.
