4agze --> SuperCharger will not power up/ Boost

[Gtsi-R]

did some testing..

direct grounded the clutch, --> OK does function.

But a direct grounded clutch does not work for driving, the ECU does not like me directly grounding the clutch so it is active all the time..
(even not with the relay removed)

the moment that I want to boost, the engine holds back big time, (no fuel of ignition I guess..

QUESTION: anyone an idea why that does not work?

I looked up a wiring diagram,



It is a relay with a diode? against disturbance I guess

Just followed the wires to the relay. and found out where the SC relay is positioned at my car.

it is a big one! in a rubber housing and part number 85931 - 12010

( the guy at toyota said acc to system for my USA GZE it has got to be 85931-30010?)

QUESTION, what is the right relay?


My neighbor got me a 5 feet hella relays with diode against disturbance,
picture like this:



exchanged the relay,
used:
86 ecu +
85 signal feed from ecu
30 ground
87 switched ground Supercharger..

but.. it did not work..

QUESTION: Is the toyota relay that much different???

QUESTION .. has someone got one of those relays for me?

Help me out please...

regards
