Guys
Has anyone pulled a 12v source from the blower fan relay?
Would like to know how you did this as I have a water pump that needs 12v.
Thanks in advance.

Ken,

Haven't had a chance....but let me take some pics of how I ran mine later today for you.

Okay...

In the fuse compartment in the engine, I used relay #2 (first picture). Just pull the relay out. I think you can re-use this relay, can't remember what type it is.

This lead (second picture) here on the relay socket is the fused constant 12V. Get a flat male spade(?) type connector and insert into it. Run it to your relay dedicated for your bosch pump. Then run a switched 12V (12V when the engine on...like the belt sensor) to activate the bosch pump relay.

The output of the bosch pump relay (blue connector in 3rd picture) goes to your bosch pump. I actually use the same output to power my air fan to draw air into the engine. Hence the temporary blue connector.

Many thanks Axl.
I have not had time to work on the car these past few days.

Your pics make it a lot easier to understand.
You are using the SAI pump - I don't have this. So I will use the blower fan relay - number 5.

I picked up a relay kit on the way home today from the auto store.

Question - where are you getting your ground from? Do you have two cables coming out from pic 2? One being the + and the other being the ground?

I revised my post a bit to make things clearer....just in case someone else need to use it.

You can pretty much use any grounding point on the car. I think there is a ground point near the left side shock tower. Look for several brown cables connected to the body of the car. Just hook up a meter to test it & make sure there isn't any voltage difference.
