I know there are lots of scattered links on this but of course i still have a couple of questions. I appreciate and help.
I'll start with what i have started 87 usdm body-91 32gt3 jdm harness and motor and ecu:
N1 color function destionation
1: g-w -check engine- 22pin pin 7
2: y-b -oil press- ea3 pin 7
3: g-w -stop switch - to spoiler stop wire on trunk/firewall
4: b-w -injector relay- not used
5: -not used supercharger only
6: y-g -h20 temp sensor- ea3 pin6
7: b- efi main relay- eb1 pin 2 & Cor
8: b-y -10 amp engine fuse- eb1 pin 7
9: not used supercharger only
10: v-w-speed 22 pin pin 9
11: l-w-cooling fan relay choose not to use
12: b-r-engine main relay eb1 pin 4
13: w-r-am2 22 pin pin 1
14: not used supercharger only
15: b-tach ea3 pin 5
16: b-w- a/c amp 22pin pin 10
17: y-charge fuse to alt ea3 pin4
18: l-fuel pump ea1 pin 12
19: g-w-stopswitch(2) 22 pin pin4
20: b-g-cooling fan relay ground (for constantly on)
21: w-b-ground ea3 pin 3(gound to pin20 and cor ground here)
22: b- electrical idle up 22 pin pin 2
22 pin connector
All the connections are above to the n1 connector or below at the COR except ecu pin 14 (fc) connects to COR 1b (some ecu's this is pin 17 on the26 pin connector)
MK1 COR connections
1a: blue ea1 pin 12 blue- black
1b: blue n1 pin 18 blue and ecu 22pin pin#14(fc)
2a: black 22pin 12,13 both back-yellow
2b: black eb1 pin 2 black and yellow and eb1 pin 1 (fan on constat)
3: black 22pin pin11 red, black-white wire from mk2 starter relay
harness, which is the wire that is on the starter soleniod.
4: green-red ea1 pin 2 green red (this IS pin 17 on the 26 pin conn. on
the 91ecu -FC )
5: not use
6: brown ground (ground at n1 pin21)
M2 connector
fat white wire -- to the two alternator wire on the mk2 harness
fat black wire -- same as above
blue wire-- fan controller not using
black-white wire- (to starter solenoid) run a wire to cor pin3 which has
- pin11 from 22pin connector STA, then branch to the
- black and white wire on the mk2 starter relay harness
alternater bolt connection:
1-fat cable from the starter bolt to the battery.
these pins not used at
EB1
pin3 blue-blk ? cooling fan warning light i think?
EA1
pin3 blue and pink
pin4 blue w red dots
pin5 blue-yellow
pin9 pink
pin10 purple
pin11 blue-blk
EA3
pin1 white blue
pin2 yellow
pin8 red
pin9 brown-blk
pin10 y-blk
pin13 red -blk
pin16 blk-y
pin17 white- red
pin18 pink
22 pin connector
3 pin - empty
7 pin empty
8 pin - power steering
15 pin - abs
16-22 empty
Well i think thats it.
