If you have the wire color and pin designation for the wiring scheme for the Pre-Glow Time Relay thanks.
My wire colors are and pin Designations for the Hella are
Green Yellow Stripe - pin 31 pin S - Green Black Stripe
Green Red Stripe - pin SF pin GF - Orange, Black, Yellow
Red - pin 15 BLANK
Brown White Stripe - pin 31SB pin GB - Blue

The pin delignations for the Mercedes are
- pin 31 pin NTC -
- pin 50 pin 15 -
- pin 30 pin G -
- pin La

If you can give me the wire colors for the pin designations for the Mercedes I can
solder and be in busines.
Thanks Charlie

I would love to help, I only have three problems.

#1 I'm at home and my wiring diagrams are at the shop.

#2 I have no idea what car you are working on.

and
#3 I don't know what you are trying to do. If you are using a relay that won't plug-n-play I would be real worried that it wouldn't play fair (bg) when it does.
