Connect STA to ignition switch or wire that goes to starter. STA wire just need's signal of +12v that engine is cranking
bro what about the wire amperage ! !! i have thick wires !! but STA is samll is it okay to hook up st2 to STA directly !!
and for the circuit opening relay doesnt it have to be a 5 pin relay ?
something like this ?
I done it. Didn't faced any problem. It's just a signal wire.4 pins will be use means normally closed pin will be free.Here are the relays i installed
thanks bro could you please give me some snaps of the ignition switch pins !! if possible !!
Will send you tomorrow. But i connected STA wire with the wire coming from starter towards cabin fuse box.
hey bro what is +B1 and + B on ECU connector 2 pin 1 and 9 ! should it have +12 positive
i olnly see +12 at pin 2 BATT on connector 2 !!
Yes both B means " + "BATT should be directly connected to battery it's the memory " + " of ecu.
i can only see + 12v on BATT , not on +B1 and +B
+B and B1 gets voltages from relay. Can be seen in Diagram i posted early.Ecu will not get ON without getting voltages at these pinouts.Check the wiring again BATT may be joined with +B and +B1.
so +B1 and +B get power when the EFI main relay is switched ?
bro i have a uncut wiring the +B1 and +b are both black wires !! i cant find where it leads to !!
okay i found where the wires lead !! its two black wires with white spots !! but bro it ends in a socket !! and to be connected to a socket in the cabin !! but my model doesn't have the same socket !! is if okay if i supply +12V at IG 1 ?
update !! on pin 9 (+B) i get +12 when i give power to fuel pump relay !! thats okay !! the other one i have to give separably to pin one ( +B1 )!! is it okay if i doo so !!
Yes its fine as it should get voltage from current opening relay (fuel pump relay)yes i also had done same.
does it have to be a always positive 12 + on (+B1) or from IG1 ??
+B1 is always positive, IG is the pinout of Ignition
okay shal i connect it to direct battery line which is always positive ?
No connect it to +B, Only connect BATT direct to battery.
ohh okay thanks !! so what else pins should have voltage present !! is it only BATT , +B1 and +B ??? is ther any other ?
