ECU Connectors & Terminals - Holley EFI

[jb427]

I'm trying to find 16/18 AWG ECU Connector Terminal (3-1447221-3). TE Connectivity shows out of stock & unavailable. And I can only find 24/20 AWG from Holley (571-136). Any other suggestions on where to purchase from?

Holley 571-136 says 18-16 gauge (571-135 is 24-20 gauge). Andrew

Any tips or guidance on how to disassemble (depin) the Mizu P25 connector? I have a couple Delphi terminal release tools, but I could not seem to get the terminals to release from the cavity. I need to pass a CAN extension cable through a firewall opening and would prefer not to cut it.

This data sheet might help: https://www.molex.com/pdm_docs/sd/521160411_sd.pdf. Andrew

That helps. Thanks Andrew!

Is Aptiv part 15336024 the equivalent 2F connector for the coolant temp sensor for what Holley actually supplies? I've been looking all night for the TPA for this connector, if there is one. Aptiv site is not nearly as informative as the old Delphi site used to be as far as the datasheet pages, plus the 2D TIF document link is broken. There's no TPS listed there or in the catalog link that Danny has linked. From the catalog picture there appears to be hooks for the TPA, but nothing listed. I really don't want to switch to the pull-to-seat connector, I'm not a fan of them.

I have a stupid question. For the CAN to USB connector, how is that wired? I see only two wires coming out of the CAN connector which are CAN HI & CAN LO. Are those simply Data+ & Data- on the USB end?

Thank you, but that doesn’t answer my question. I know the pin-outs for the CAN connector. What I’m asking for is if the USB DATA+ goes to CAN HI and USB DATA- goes to CAN LO. I want to make my own CAN to USB cable.

Holley uses a proprietary CAN protocol so you have to buy their (over-priced) cable. Similarly, Sniper "Config" and Datalog files are not compatible with the more advanced Holley EFI free software that uses "Global" files. Clever folks can probably reverse-engineer the adapter harness, but then you have to fuss with the Mizu P-25 connector and setting up the CAN USB adapter with workable firmware. The attachment is a Holley document of troubles from when they switched the USB adapter firmware due to Windows 7 driver update issues. Basically, if you have the time and enjoy tinkering you may get there, but it won't be easy.

Gotcha. With the USB end on the Holley cable so small and only two visible wires coming out of the middle two terminals of the Mizu-P25 connector, I was under the impression it was simply a wired connection to termination points on either end. Thanks for the info! And thank you Danny for such an in-depth thread!

I'm looking for the connector & female pins for the Sniper HyperSpark to coil harness. It's a three cavity connector using the two outside cavities with orange & black 12 AWG I believe. Any help is much appreciated.

[Danny Cabral]

Is this the coil connector you're looking for? https://forums.holley.com/showthread...360#post106360 (Related Forum Thread)

Yes, but only the inside connectors.

If you mean terminals, it's the last link listed in that post (LINK).
