ECU Connectors & Terminals - Holley EFI

What's the connector for the Holley wideband O2 sensor to plug into? I just bought two of the 554-101 sensors. Thanks.

What's the connector for the Holley wideband O2 sensor to plug into?

The WBO2 sensor connector is a black, eight cavity Delphi Metri-Pack 150 Series connector with eight male terminals.

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".

The LSx coil output connectors are 7 pins in an "8 pin" style housing. Is that number 12047938, a Metri-Pack 150, or is it something else?

Yes, the Delphi 12047938 is a Metri-Pack 150 Series connector.

Just to add to the thread, I just ordered these from Mouser. I believe this is the 3-way, black GT 150 Sealed Female Connector Assembly, Max Current 15 amps.
Part #15477863 used for the transducers. My transducers came with pigtail connectors, but I want to terminate them to my original harness without splicing.

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.

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.
