ok so my st205 water pump is hooked up just as it is on the edw except since i didnt have a relay for it so i just ran the wires around the would be relay.
im drawing my power from the cds fuse just like it shows on the ewd and the ground is also ran just like it is on the ewd. the other three wires from the pump hook up to the corisponing wires on the ea1 connector which feed back into the ecu just like it is on the ewd the level sensor has been tested and found that it does close and complete the cuircut i checked continuity between the ecu and sensor plug and fount that im not getting a signal from the ecu to the sensor...... ........ anyone know what kinda signal is sent out from the ecu to the sensor which goes from the sensor (if closed) and to the ground. |

ohhhhhhhh
would i have harmed the ecu by one having the pump on all the time two by having the wire from the 7.5 ign fuse wire connected to the int ecu wire all the time with no relay inbetween. This post has been edited by urbandork: Dec 6, 2006 - 12:43 PM |

Having the pump running all the time won't hurt it but I'm not so sure about INT. Only one way to find out. Hook it up right and see.

He's currently using my ECU (luckily it was the same P/N). I'll be fixing his so he can use it again. AND it was an incorrect relay - normally closed instead of normally open. (he didn't get the correct on with his clip) All is fixed and the car is nice and fast.  -Charlie PS. Craig, I could hear you until you got to the freeway. Your car sounds pretty good.
