ECU Connectors & Terminals - Holley EFI

[Danny Cabral]

My transducers came with pigtail connectors, but I want to terminate them to my original harness without splicing.

But that appears to be the same connector that's included with the Holley EFI transducers (Delphi 15477863).
You could have just purchased the connector terminals separately, for the Holley pigtail assembly.

I think there's a misunderstanding here. I wanted the connectors without the pigtails, so I could add my transducers to the system and only needed the connectors. Holley wouldn't sell me just the connectors, so I searched everywhere, using mostly data you provided throughout your thorough posts, and came up with these connectors. So I figured I would just add the info I came up with to hopefully help out anyone in the future, to not have to search like I did for these goofy little connectors. :)

Your posts are incredibly helpful and very much appreciated.
If you had a donation account, I would gladly forward you some money.
You devote a lot of your time into this, and I appreciate it.
Your knowledge base of this Holley EFI system is awesome.

TPS Connector?

Anyone know the part number for the TPS connector? I think it's a Delphi Metri-Pack 150 Pull-To-Seat, but not finding it in the Delphi catalog?

[Danny Cabral]

Some of the sensor connectors (such as TPS, MAP, A/C, Fuel & Oil) are Delphi GT 150 Series, with the different colored "key index" insert.

The Metri-Pack 150 sensor connector (TPS, MAP, A/C, Fuel & Oil) is not a Metri-Pack Series 150.2 connector body (LINK).
#12103881 16/18 AWG (1.0-0.80 mm²) Metri-Pack 150 "Pull-To-Seat" terminals.
#12089290 20/22 AWG (0.50-0.35 mm²) Metri-Pack 150 "Pull-To-Seat" terminals.
The Delphi Metri-Pack 150.2 terminals have a flag for the newer slotted connectors (flat connectors, not round like TPS).

If you're installing an additional transducer (as opposed to repairing an existing transducer connector), the
Delphi Metri-Pack 150 connector is much better (LINK). I don't like the Delphi GT 150 style connector (LINK).

Danny, do you know the part number for the harness side 8-way Metri-Pack connector for the NTK WBO2? Is the CAN connector a Metri-Pack 150?

By the way, thanks to all the help on here (and some other places too). I made my own main harness for my dragster.
Also made my own 16 injector harness. Car runs good. I do have one WBO2 working out of P2A, and need to get the primary one going, so I can try Closed Loop.

[Danny Cabral]

Danny, do you know the part number for the harness side 8-way Metri-Pack connector for the NTK WBO2?

See posts #8 & #14. It's a black, eight cavity Delphi Metri-Pack 150 Series connector:

FYI: These Delphi Metri-Pack connectors are color coded with corresponding slots.
If plugging into an existing connector, the color of the connector isn't a "choice".

Is the CAN connector a Metri-Pack 150?

Yes.

Danny, do you know what the terminal connector (ECU side) is on Holley 558-200 Injector Harness? What about pin-outs? Thank you in advance.

[Danny Cabral]

Danny, do you know what the terminal connector (ECU side) is on Holley 558-200 Injector Harness?

The fuel injector harness connector is a gray, ten cavity Delphi Metri-Pack 150 Series connector with ten female terminals.

Does this information relate to the Terminator EFI as well? Looks like a lot of the same connectors are used. Thanks.

Most of the connectors are the same. The Terminator has a different main harness, so some of the connectors are different.

As always Danny, thank you for your help!

Using a Holley 558-104 main harness. Looking for some information on the Delphi Metri-Pack 150 series terminals.
Interested in the Delphi part numbers, since all 150 series Metri-Pack connectors are not the same. Thanks.
1. Looking for the air\water temperature terminals.
2. Looking for the transducer terminals.
3. Looking for the large male end going into the injector harness.

1. Looking for the air\water temperature terminals.

http://www.powerandsignal.com/docs/D...%20Catalog.pdf (Delphi Connection Systems Catalog - Page 2.22, 8.2 & 8.9)
Depending on the coolant temperature sensor connector, it's either a GT Series 150 3.5 mm, or a Metri-Pack Series 150/150.2.

2. Looking for the transducer terminals.

Danny, thanks for the information.
I looked up the Delphi information you provided, and it looks like the transducers and air/water sensors share a similar terminal.
The Delphi part numbers for the ones I found are the following: #15326266 & #15326267. Thanks.

However, I'm still confused about the main harness connecting to the injector harness.
The Delphi link is not showing it. It's the pin leaving the main harness, looks like a male end.

[Danny Cabral]

Yes.
FYI: Don't confuse the GT 3.5 mm centerline terminals with the Metri-Pack 150/150.2 series terminals.
Both are very similar "Pull-To-Seat" type terminals. Look closely at your terminals before ordering:

Yes, use the 0.50-0.35 mm² terminals for the small 22 AWG transducer wiring.
