Hi all,

Just finished changing my seats out in my '89 300e. The donor seats were from a '95 e320 and they have the heated seat option. The rear seat and passenger seat were a direct swap. The drivers seat was a different story. I had to swap out the main board that the wire harness from the car plugs into. Has anybody successfully added heated seats to a w124 using the stock parts? Does anyone have a list of the parts needed?

Was the drivers side not an easy swap because of the heated seats? If not for heated seats, would it have simply been "plug and play"?

donor car had 86k on the clock. There is a different plug for the seat heaters on the bottom of the seat. My harness had more pins than the 95's seat. The 89 seats had the memory function for the drivers side didnt check to see if the 95 did as well but i'm pretty sure it was a standard feature.

1995 did not have memory driver's seat as standard - it was an option with 2 memory features. that could be the reason why your 89 harness has more pins.

as my previous post described the seats that I upgraded to are heated and would now like to go ahead and use this feature. Does anyone have a parts list needed...harnesses, relays, switches and their associated part numbers? Those of you who have completed this task please chime in...your input will be appreciated.

Been there, done that. I put E500 seats in my 1987 300D and made the seat heaters functional. You'll need the two wire harnesses, relay, both switches, and the console wood. And, then you'll need to rip out the whole interior to install that stuff (seriously). Photos of my seat install are here:

There's a different thread here where I posted more info:

What are those gauges for? Any performance mods?

From left to right... intake air temp (IAT), exhaust gas temp (EGT), and boost pressure (PSI). I'm planning on cranking up the power a bit. I've already increased the output of the stock injection pump a little, and now I'm working on having a spare pump modified to push more fuel. Current output is probably 160hp, the limit of the stock pump is 175-180hp, and after the hybrid pump is installed I'm hoping for 200-220hp. Long-term my goal is 275-300hp at the crank. I'll need to change the turbo and add an intercooler, make more significant mods to the pump, plus a few other odds & ends to get near 300hp though. I'm not interested in getting 400-500hp like the SuperTurbos in Finland... too many mods, too expensive, too much chance of grenading the tranny!

:thumbsup:

I didnt know you were running a turbo...that makes sense now. What kind of turbo do you have? How about the exhaust?

Sorry - I should have clarified. This is a 1987 300D turbodiesel... the stock turbo is a Garrett T3, or KKK something-or-other of equivalent size. Mine has the KKK. Exhaust is stock diameter but with the center muffler replaced with a straight pipe. I'll be installing a Remus rear muffler from a 500E (larger diameter input pipe) along with a larger exhaust (probably 3-inch or so) when I upgrade the turbo in the future.

just curious, i see that on your dash you have two AC recirculation buttons, on by the window switches and the other by the emergency button. Is this something you have added and if so, what is the difference between the two. I have never seen two in a single car before.

Good catch. ;)

Yes, this is something I added, but it has nothing to do with the HVAC system. The recirc switch just happened to have the proper electrical contacts, and LED, that I needed. The recirc switch by the window controls is for my Valentine-1. The switch triggers a latching relay, so when it turns on, the relay latches on, triggers the LED, and turns on the V-1. I can either turn it off with the switch, or when I shut the engine off, this also turns it off.

The reason for all this is so that the V-1 automatically shuts off when I turn the car off. I was sick of getting in the car, turning the key on, and listening to the screeching startup beeps from the V-1 since I always forgot to turn it off! And there's no way to disable the startup self-test on the V-1.


BTW - the original seats from my 1987 (and door panels, etc) are all for sale. I just haven't had time to post them in the classifieds yet.

i been lookin for a grey driver seat for my 95 e320 any suggestions?
Call Pat Bartholow at Potomac German, 800-831-7686 ext#206... he can probably get you a good driver seat (note that with & without memory are different, unless you swap the bases w/ motors... not a big deal). Tell him Dave in Idaho sent ya. ;)
