sv k3 Instrument wiring?

ok so im going to try and figure out how to wire up the stock clocks (with minimal wiring) to set the TPS

so far i can figure out that i need 12v and - to power the clocks then ether the black + green wire going to the clocks from ECU or brown + black wire coming from the ECU all the other wires lead to something those are the only 2 that dont go any where apart from the ecu

can any one make heads or tails on this ?

all i need the clocks to do is display the tps position i will use the vapor tach along with stock clocks

wires BR/B and B/G at the clock are the ones that i think i need ? they both go the the ecu but after that i cant trace them back ?

and the wire from the TPS is p/w that goes to the ECU as well
