Relais Frame ...

29 June 2019

 

With original old Mercs, the electrical components are somehow "distributed" under the dashboard, hardly accesible and difficult to find.

So I came up with the idea, to put a wooden plate behind the gloves compartment and install ALL fuses and electrical components there. As not all fit, I will put e. g. the seat heating Relais behind the centre console.

However, the Relais were a topic. Indicator, overvoltage protection, electric windows, kick-down, etc. etc. … all "somewhere". So I got a nice holder from a W126, where the connectors are clicked-in from underneath and you just put the relais on top. However the W126 before 1985 and after didn't fit my purpose.

That's when I thought, I design it myself and print it. All arranged according to size and space and - most important - all together. Even the two modern relais from the Bantam Aircon will be replaced by "old" Merc relais.

As the original case of the cruise control relais has some "ears" for installation, but I wanted to have it closer to the other relais, I designed a new case for it ;-) ...

And the cruise control relais with a new case and proper labeling ...

I don't know about you, but those pin assignments can be quite mind-boggling ;-) … Plug or socket, upside down or not …

So as I do a complete new harness, I did ONE layout now and - hopefully - when connecting all the cables there are no mistakes!
