Miata Turbo Forum - Boost cars, acquire cats. - Miata OEM and aftermarket connector guide

Note: this thread is migrated from data I've had in spreadsheets for several years.

I will scan for typos while expanding this. I will remove this notice when I've adequately re-re-re-proofread this.

This thread is meant to make it easy to source parts for working with connectors that frequently appear in stock and modified Miatas. There is some of this data scattered around here and there, but this is intended to be a comprehensive guide based off manufacturer catalogs. This thread is just for part number data.

Search part numbers in Octopart before you buy. You'd be amazed how cheap some of this stuff is.
The connectors are alphabetized by function.
Device connections are labeled as "harness side" and "device side" by default.
The terminal you use will be a function of your wire gauge.
The seal you use will be a function of your wire's insulation OD. This is a function of both gauge and type.
Recommended terminal/seal combinations are listed for popular sizes of TXL wire.
The terminal recommendations will work for any wire of the same gauge.
Users of non-TXL wire will have to figure out the insulation OD of their preferred wire.

Data is sourced from the following references (hotlinks may die):

Cam Angle Sensor (CAS, 90-97)
Harness side: Sumitomo 6195-0030, DL series 4-position female
20awg TXL: 8100-1427 female terminal (22-20awg) + 7165-0118 seal (1.7-2.4mm, blue)

16awg TXL: 8100-1428 female terminal (16-14awg) + 7165-0118 seal (1.7-2.4mm, blue)

Device side: no true OEM mate. An aftermarket mate is sold by Ballenger Motorsports as P/N CONN-100937, using TS-series male terminals.
For this aftermarket mate:
20awg TXL: 8100-0457 male terminal (22-20awg) + 7165-0118 seal (1.7-2.4mm, blue)
18awg TXL: 8100-0458 male terminal (20-16awg) + 7165-0118 seal (1.7-2.4mm, blue)
16awg TXL: 8100-0458 male terminal (20-16awg) + 7165-0118 seal (1.7-2.4mm, blue)

Coil Packs (LS2 D585 coils)
Harness side: Delphi / Aptiv 15439568, GT 150 3.5mm centerline (3.5CL), 4-position female, key index, no shroud
18awg TXL: 15326267 GT 150 3.5CL female terminal (18awg) + 15305351 GT 150 3.5CL seal (1.7-2.1mm, yellow)
Required TPA: 15305351

Device side: not available

Note: these coils were originally intended to mate with a 4-position Metri-Pack 150 pull-to-seat (P2S) connector. The GT 150 3.5CL variant is cheaper, easier to use, and streamlines crimp supplies and practices. By substituting GT 150 3.5CL for all Metri-Pack 150 P2S applications in a DIY project, one crimp tool that supports GT 150 terminals can be used for the majority of common aftermarket EFI parts.

Coil Packs (90-93 coils)

Coolant Temperature Sensor (NB CLT, 1999-2005)
Harness side: Sumitomo 6189-0179, TS series 3-position female (T-type keying)
20awg TXL: 8100-0460 female terminal (22-20awg) + 7165-0349 seal (1.4-2.0mm, brown, 6mm terminal pitch)

Coolant / oil temperature sensor (CLT / OT, GM closed-element sensor)
Harness side, no shroud: Delphi / Aptiv 15449028, GT 150 3.5mm centerline (3.5CL), 2-position female, mushroom index, unshrouded
20awg TXL: 15326266 GT 150 3.5CL female terminal (22-20awg) + 15366022 GT 150 3.5CL seal (1.47-1.85mm, green)

Required TPA: 15452678

Alternate harness side, with shroud: Delphi / Aptiv 15336004, GT 150 3.5mm centerline (3.5CL), 2-position female, mushroom index, shrouded

Device side: not available

Note: unshrouded is, IMHO, often easier to disconnect. Like many other connectors in this list, this GT 150 variant is the preferred alternative to an older Metri-Pack 150 Pull-to-Seat variant, allowing streamlined terminal inventory and assembly at reduced cost.

Crank Position Sensor (NB CKP, 1999-2005)
Harness side: Sumitomo 6195-0012, DL series 3-position male
20awg TXL: 8230-4472 male terminal (22-20awg) + 7165-0118 seal (1.7-2.4mm, blue)

16awg TXL: 8100-1428 female terminal (16-14awg) + 7165-0118 seal (1.7-2.4mm, blue)
Mounting clip (optional): Sumitomo 6810-2653

20-16awg wire: 770854-1 female terminal (tin) or 770854-3 female terminal (gold)
Note: seal is integral to connector.

ECU (MS3 Pro / Ultimate / Evo)
White connector, harness side: TE AMPSEAL 776164-2, 35-position female, natural color
Gray connector, harness side: TE AMPSEAL 776164-4, 35-position female, gray color
Black connector, harness side: TE AMPSEAL 770680-1, 23-position female, black color
20-16awg wire: 770854-1 female terminal (tin) or 770854-3 female terminal (gold)
Note: seal is integral to connector.

20awg TXL: 12191818 GT 150 female terminal (22-20awg) + 12191152 GT 150 3.5CL seal (1.20-1.85mm, white)
18awg TXL: 12191819 GT 150 female terminal (18-16awg) + 12191153 GT 150 3.5CL seal (1.86-2.25mm, blue)
16awg TXL: 12191819 GT 150 female terminal (18-16awg) + 12191153 GT 150 3.5CL seal (1.86-2.25mm, blue)
Required TPA: 15452678

Device side: not available

Note: there are multiple variants of USCAR injector connectors from different manufacturers. The GT 150 variant streamlines crimp supplies and practices by consolidating around the GT-150 connector family.

Injectors (OEM, 1990-2005)
Harness side: Sumitomo 6189-0039, MT series 2-position female, high keyway, 5mm pitch

16awg TXL: 1500-0110 female terminal (20-16awg) + 7161-9785 seal (2.0-2.7mm, black)

Device side: no true OEM mate, aftermarket mates sold through many channels.

Intake air sensor (IAT, GM open-element sensor)
Harness side, no shroud: Delphi / Aptiv 15449027, GT 150 3.5mm centerline (3.5CL), 2-position female, key index, unshrouded
20awg TXL: 15326266 GT 150 3.5CL female terminal (22-20awg) + 15366022 GT 150 3.5CL seal (1.47-1.85mm, green)

Alternate harness side, with shroud: Delphi / Aptiv 15335987, GT 150 3.5mm centerline (3.5CL), 2-position female, key index, shrouded

Device side: not available

Note: unshrouded is, IMHO, often easier to disconnect. Like many other connectors in this list, this GT 150 variant is the preferred alternative to an older Metri-Pack 150 Pull-to-Seat variant, allowing streamlined terminal inventory and assembly at reduced cost.

Knock Sensor (NB, 1999-2005)
Harness side: Sumitomo 6195-0006, DL series 2-position male

16awg TXL: 8100-1428 female terminal (16-14awg) + 7165-0118 seal (1.7-2.4mm, blue)
Mounting clip: Sumitomo 6810-2653

Pressure Sensors (nearly all aftermarket pressure sensors with 0-5v outputs)
Harness side: Delphi / Aptiv 13602480, GT 150 3.5mm centerline (3.5CL), 3-position female, round
20awg TXL: 15326266 GT 150 3.5CL female terminal (22-20awg) + 15366022 GT 150 3.5CL seal (1.47-1.85mm, green)
18awg TXL: 15326267 GT 150 3.5CL female terminal (18awg) + 15305351 GT 150 3.5CL seal (1.7-2.1mm, yellow)
Required TPA: 15452678

Device side: not available

Note: these pressure sensors were originally intended to mate with a round, 3-position Metri-Pack 150 pull-to-seat (P2S) connector. The GT 150 3.5CL variant is cheaper, easier to use, and streamlines crimp supplies and practices. By substituting GT 150 3.5CL for all Metri-Pack 150 P2S applications in a DIY project, one crimp tool that supports GT 150 terminals can be used for the majority of common aftermarket EFI parts.

Throttle Position Sensor (NB TPS, 1999-2005)
Harness side: Yazaki 7283-1133-10, 090 II series 3-position female with dual keys
20awg TXL: 7116-4025 female terminal (22-20awg) + 7157-3821 seal (1.4-2.1mm, dark green)
18awg TXL: 7116-4026 female terminal (18-16awg) + 7157-3646 seal (1.9-2.9mm, brown)
16awg TXL: 7116-4026 female terminal (18-16awg) + 7157-3646 seal (1.9-2.9mm, brown)

Device side: not available

Note: None of these seals are widely available in the USA. A common, dimensionally-identical seal is Sumitomo 7160-8234 (MT series 6mm pitch, 1.7-2.7mm, black, 5.7mm lip / 5.8mm length).
