Starion Turbo swap question #1076333 01/15/15 08:32 PM

So, i read through the Turbo bible and i'm at this point...


The B-38 connector is the graft point for the starion system into the Monty. It's on the Starion harness, and I think it lives in the Starion under the glove box, but the manuals on cd I have (88 Conquest) are missing the harness layout pages 8-36 and 8-37 (and I'd love to have a scanned copy at the best resolution you've got of those!). I do have the circuit diagrams, and here's the basic wiring you need to do. All wire color codes reference the ecu side of the B-38 connector, a male 14 pole connector. L is blue, B is black, Lg is light green and the others are evident. First letter of the color code is main wire color, second is color of tracer stripe(s)The number is the mm2 cross sectional area of the wire - bigger is fatter, no # is 1mm2 xsect. area. Orient the plug so the L (blue) wire is at the center top position. That's #4. Number l>r and t>b.

1 not used
2 2-BY Necessary - wire to ign switch start position 12V+
3 1.25-B Necessary - wire to Batt. + with fuse protection
4 2-L Necessary - wire to ign sw. On position 12v+
5 not used
6 RB necessary?? - wire to Batt 12v+ w/ fuse = amps of SQ multipurpose fuse
7 not used
8 (first of bottom row) LgB not needed - used in SQ for faking the boost pressure on the LED gauge
9 YG optional but nice to have - wire to Monty speedo reed switch circuit*
10 not used
11 2-BY Necessary - wire to ign switch start position 12V+
12 BR nice to have - trouble code output - wire a jumper wire to put it in reach, and use a voltmeter to read the trouble codes (all 6 of them)
13 not used
14 not used

If you can when you get the donor stuff, get about 6" of the hrness and the other half of the B-38 connector, so you have a plain butt splice. The old Monty carb ecu connector will have many of the various 12v+ inputs you need. Consult your Monty manual for the pin out, and you can use the ecu harness side of that connector with a few inches of wire to make the butt splices to the 6" of wire on the female half of the B-38 connector noted above.

* Try getting a pulsed 12v signal on the yellow wire at the 4wd indocator light relay box on the C-28 connector at the box on the passenger side footwell wall or the C-6 connector at the rear of the instrument cluster (on an 87 Monty) for this connection.

Now i may have skipped a step, I have already routed my harness and tucked the ECU under the dash behind the glove box. I left an 8 blade male connector just on the other side of the bulkhead/firewall from the ECU as it had the wires with the colors matching the above description.

Well now i've noticed it's a male 14 pole connector, that must be one that plugs directly into the ECU? or is the other 8 blade connector the same group of wires and i can use that? Do i need to dig out that ECU?

Sounds like the 8 pin connector you describe might be for the main relay, aka the fuel pump relay.
