Hello group,

It has been a while since my last post. I have learned recently that it is possible to use a Glow Plug Relay from a 90-91 350SDL 6 cyl in the 87 300D turbo . Can anyone confirm this ?
Is the relay in the 350SDL's a pre+post glow unit ?
The Duraterm glow plugs are available for about $ 13.00/ea
Since nobody offers a conversion kit for the 6 cyl 300d, would this be an alternative ?
The relay is $ 99.00 but being an electrical part is not returnable.
I would appreciate any advice on the matter. Would it plug into the harness or would it need a new plug ?
The most important issue is, however, to be a pre+post glow relay to smooth out the cold starts and smoke.
Thanks
