1st.. On the harness there is a light gray wire coming from the relays... Is this the wire i connect to Key on power from the vehicle that turns everything including the ECu on?


2nd.. why are there two grounds from this relay? engine and battery ground?


3rd.. is the black yellow wire from pin 33 to fuel pump relay a ground that the ecu uses to turn on the fuel pump?

4th... Can anyone tell me how to wire the second gen CAS which i posted another thread about?

is it just the 4 cas wires to the 4 wires in the shielded harness? \/ \/ \/

THANKS!!!!

 

1 - Yes

2 - Fatty to batty, small to chassis. Not really sure how important having 2 grounds there is, but doesnt hurt

3 - Yes

4- read this 1300cc 2nd gen E6K install

 

Thanks! Btw just finished reading the whole manual...

 

okay so I don't need the other wires... Just 4

 

... I spent quite a while on editing the guide for a S5...

4 cas wires to the 4 wires in the shielded harness?
Strangely enough on a S5 JDM only Green-Green so 1 of 4 are the same color but
All generations are the same otherwise... That was a headache.

depending on how far your willing to go I would probably go around and use a wheel or HES(hall effects sensor) to advoid CAS. (my timing was off, did little dammage)

 

yes im talking 4 CAS wires to 4 wires in shielded harness....


like in this diagram...

I have a second gen CAS but have a 1st gen car 12a originally... also how do i run the factory tach? can i just tap into one of the wires off the CAS or have to use an output from the E6K?
