Starter Inhibitor Switch Electrical Conniction

Dear Mr. Henderson

I understand your point. When ordering ask for the emission control harness, because that is always a separated additional harness.

There are many add on harnesses on MB pagodas and other similar cars made by Mercedes on the same era.

Harnesses:

1. MAIN HARNESS. this could be LHD, RHD, for AUTOMATIC transmission or MANUAL
2. REAR HARNESS. this could be LHD or RHD
3. AIR CONDITIONING HARNESS, always as an ADD ON harness
4. DEFROSTER HARNESS
5. SUN ROOF HARNESS, for cars like w111 coupés or W108/109
6. POWER WINDOWS harness
7. and finally EMISSION CONTROL HARNESS, this could be for MANUAL transmission or for AUTOMATIC.

Mercedes always built harnesses as ADD ON to a BASE SHARED harness among many cars of the same chassis number designation.

What I am trying to say is that you will not find one BASE harness with all that functionality on the same CORE.  Those functions are always provided by additional harness that fit like a LEGO on the base one.

Best regards
L.Peterssen

CJ,
I feel your pain but:
They (SLS) are actually pretty detailed when it comes to ordering a harness. I was going to get one from them as well but bought one from a forum member instead.

After reading all of the great posts on this problem that I'm facing, my 280SL/8 is without a doubt a very late 280SL and it appears what was sent to me was a wiring harness for an early
280SL. Then to have to make an addon harness which in the end will have cost me over $2500 dollars. So, with that in mind I'm thinking just to wrap this harness up and sell it on Ebay and turn around and reorder it from another harness company based in the US this time.

If i were in your position, the only two options i would consider, is to 1. order the add on harness from Leo Peterssen, this would be far less expensive than starting from scratch, and more chance of being correct than from any other supplier, or 2. consider doing away with the emission control system, relatively simple and inexpensive (when compared to other options) from what i've read on here, and lots of posts as to how to do it

Very good points but to do away with the emission control system will cause more problems that could become another headache.

Do anyone knows what kind of terminal connector are used at the two oil pressure switches that are part of the system, circled in green on photo attached below?

Hi,
the size of the oil pressure switch connector eyelet is 4,4 x 1,8 x 8mm.

Many thanks WRE for that info. So it has the standard eyelet size used on every terminal as in main fuse box.

CJ,
Please elaborate.  If I recall correctly, people have posted on this forum that it is not a problem, so interested in your opinion/experience.

Well to start off with, this car was built with an emission system installed which means that it receives signals from the transmission, fuel control, timing, and vacuum system among other inputs like 17c degree and 100c degree switches. Not to mention I'm restoring this car as close to original as possible. Not much else to explain I guess.
