whats going on guys. i finally did my harness on my car but i need help asap. the only thing i need to run is fuel and ignition. the part that im confused at is where do i have to run it to. do i run it to the relay box under the hood that says fuel pump and ignition or do i run it straight to the fuel pump and straight to the ignition. can someone please help. below is info that i obtained from another site.
Ignition --- F9 --- This is much easier to wire as the ECU does not control ignition timing. Simply run the Grey wire to the ignition coil +ve side and run the brown wire to the ignition coil -ve side. If you have any difficulties with erratic rpm readings then some adjustments will need to be made. As with the E6S above, the black end cap of the ECU must be removed and inside are a bank of DIP switches. These are used to configure the voltages for the rpm pickup of the ECU. Only change them if you are experiencing problems. Switches 2 and 3 turn on and off the filters and these should be the only switches you will need to move. Find the combination that gives the cleanest rpm readings.
PRETTY PRETTY PLEASE GUYS..
"Wiring Wiring the rest of the system is easy , and I will cover it one day. All that is basically needed is to follow the instructions in the manual. The only slightly confusing point for most people is the wiring of the fuel pump relay. In fact it is already wired and relayed. The two orange wires that you have to connect are very simple to do. One of them ( any one ) goes to the battery +ve terminal as it must have constant 12V , and the other orange wire goes to your fuel pump +ve. The other terminal on your fuel pump goes to earth. You will also have a thick Red and a thick Black wire. These will go direct to the battery with the Red going to the Positive + side and the Black going to the Negative - side. There is also a grey wire that should go to a 12V source that is switched by the ignition key. A good place is where the ignition coils get their power."
