Do you know the pinout of the egrs? 1377 - 1378
Looking for the 5v line

Also for the air mixer position connector and power steering sensor connector.

Appreciate it big time.

1377
1316 : "EGR" motor A- control
1308 : "EGR" motor A+ control
13C0 : supply +5V CM VCC1
406A : "EGR" a earth
133 : "EGR" repeat information A

1378
1426 : "EGR" motor B- control
1327 : "EGR" motor B+ control
13C0B : supply +5V CM VCC1
406B : "EGR" b earth
138 : "EGR" repeat information B

1346: Air Flow Sensor A
13A3 : frequency air flow sensor signal A
0007: Unknown
13E3 : earth
1340 : air temperature at the air flow sensor signal


1347: Air Flow Sensor B
13B3 : frequency air flow sensor signal B
0007b: Unknown
1336 : air flow sensor earth

However 0007A & 0007B are obviously the power from the engine fusebox as the wiring changes to BM10A at Pin 24 of the 28 pin black connector at PSF1 and is fused by F10.
