I work with my "new" T25 and I try to resolved all problems which i found. I am after change interior fan, heating valve string, and more small things. Now is time to connect with proper order all cables on the engine. Previous owners work for years to prepare something like this (please see photo) - maybe someone can help me please to find where "it" should be connect:



1(white and red arrows) - brown colour cable connected at front engine - close to oil filter - it is sensor or switch -do you know what it is? Unfortunately second end is in plug 3 and isn't connect anywhere - I don't know where should be go.
2 is connect to the oil pressure switch and this is working ok - second end similar to 1 is in plug 3 but is extended to the diode on dashboard.
4 blue - green - like on the picture - cut out - ?
5 violet - black - like on the picture - cut out - ?

Do you have any ideas?

If you have a haynes it is set out in there.

the sensor at the front of the engine is the high oil pressure switch. mines not connected either ..the brown wire for it is just earthed as I have a pressure guage
and the other (no 2) is the low pressure switch. (oil light)
The purple and black wire should be connected to the temp 2 sender on the thermostat, which has a black wire (power) to it aswell (post 86 ) then it goes to the No1 relay in the junction box on the bulkhead (left). this triggers the relay to power the thick red wire (manifold heater)
Coming out of the yellow connector (thick red cable for manifold heater) should be another black wire to the choke heater on the carb

what a mess

now what is that blue wire.. I'll take a look in the morning

Thank you kevtherev - tomorrow after work I will try to back with connections as like your information . Good night.
