hey guys. i have an 86 300e and have a couple of questions about the lcd display/sensor. the lcd display i have currently in the car plugs into a square 4 pronged plug. i bought a newer lcd display from a 89 w124 that has five prongs. now apparently, there is a part, 013 545 32 28, that can allow the 5 pronged display to plug into the stock 4 pronged plug. have any of you guys ever heard of this part or swap?

another question is that when i look at the 4 pronged plug in the car now, it actually has 5 wires. is it possible to just cut and solder the individual wires to new lcd display?

thanks again.

They're in numerical form 1-1 2-2 3-3 4-4 5-0 (in your case, you don't want tha fifth prong on the LCD unit)...you can either open the unit up and remove the extra prong or just cut it..
