I am trying to locate the 5-pin plug used in the glow plug relay connections for these models from 90 to 93. I am converting my 300SDL to an afterglow relay. The 300 has a 4 pin plug in the relay box and the later ones with afterglow have a 5 pin plug. Does someone have the plug or the wiring hardness for the glow plugs from a wrecked vehicle?? Would very much like to find a plug so the installation is clean.

Thanks

015 545 96 28 for the housing, 002 545 99 26 for the terminal. It was $5.60 for the housing and freaking $4.32(!!!) for the terminal plus tax at the dealer a couple of months ago. FWIW, the fifth terminal slips over the pin with the 4-position housing in place, which is how I had it until the special ordered housing came in. The 5-position housing isn't a must.

Temp sender 005 545 03 24 (and a cup of coolant) replaces the 50*C switch in your SDL. It's a $10 part online. The alternative is a temp sender in head or upper hose turret like 602s have. I tapped the fifth wire into the harness for the 50*C switchover valve to reduce custom wiring.

Thanks for the information. Sorry to be so tardy in responding but was out of town on a work assignment for a week.

I had planned to wire into the switchover valve but had not thought I needed to change the temperature sender. What is the difference with that sender you referenced and the original on the SDL?

Thanks, Frank
