Barrometric Preasure

TT

AC Clutch, Just a load switch to up revs at tick over and cut under WOT
Knock (maybee 2), just the one.Its a high compression motor.
EDIS, Not seen an external edis on anything 1990> thats not an auto trans'
Variable Steering control, seperate ecu but it is connected by can-bus.

So yep we have,

4 injectors, 2 wires each.
ISCV, 2 wires.
TPS, 3 wires.
ECT, 2 wires.
Knock, 2 wires.
Cat 1, 4 wires.
Cat 2, 4 wires
IMRC, 4~5 wires I cant remember of the top of my head.
MAF, 6 wires but has Iat built in
CPS, 2 wires.
Phase Sensor, 2 wires.
COILPACK, three wires.
VSS, 3 wires.
fuel rail preasure, 3 wires.
Barrometric Preasure, 3 wires.

Also you have the
fuel pump driver modual.

There will come a point where you cant run a high emissions engine with out penalties. Some eu countrys already tax kitcars bassed on there emmisions.

Its not that hard if you brake it down into blocks. ie

start with putting the ecu where you want it.
Run the wires for the injectors. Thats one switched live and four earths to the ecu.

keep going with any one of the above and finish each one before starting the next. One weekends work will give you a full loom to wrap and thats it no messing, no tunning just plug it all in and play.
