Anyone know how to replace a Molex 150 connector?

Best guess is that the lower number is just a date code.
Try to find a pin extractor; that would push in from the front and release the pins, one at a time. You might have to release the back piece first. See if this helps:

Refer to this document from Molex: https://www.mouser.c...ectorsystem.pdf
Look at page 8, at the male type, to see how the back assembles. You look to have the male side. You have to pull out the 'seal cap', which has small lock tabs on each side that catch in holes in the body. IDK if you got a new seal cap or not....?? Once that is out, you can slide it and the orange seal back on the wires. If the tabs break on the seal cap, then you may need to glue it in or buy a new one and re-assemble. But IDK if you can slide a new seal cap and seal on the wires with the terminals already crimped in place. So just try to gently get that seal cap out, and take a bit of glue with you to use 'just in case'.
- Pull back the seal cap and seal on old housing and leave hanging on the wires..
- Before you release the pins from the old housing, or insert the pins in the new housing, you have to slide the 'TPA' forward in the front of both housings. Look at the bottom section on page 33 to see how to slide this out on both old a new housings; I think your red arrow points to where you grab the TPA to slide it out/in.
- Then remove the wires/pins on the old housing; your blue arrow shows where to insert a pick or paper clip or extraction tool to release the pins.
- Once you have re-inserted the wires/pins in the new housing, then slide this TPA back in.
- Then re-install the seal and seal cap.

Wow, If I’m reading it right I can use the the old seal and seal cap to simplify the install. Thanks again.
Yes, that is the way I am reading it too. R&R of the seal and seal cap seems dubious with the pins still crimped on the wires, so I would try to just replace the connector body.

Following since I'm installing heated seat elements in a 1+1 seat. They are arctic cat with the same exact molex that is on my Enduro. Hopefully I don't have to take apart the molex if they are reversed or something.
Let's hope they are not reversed. If so, then you are going to have to change the connector from male to female, or vice versa, on one side, and that will require changing the pins on the wires too. Reliable crimping requires a correct crimping tool; those are not cheap. If it comes to that, then you may need to add a tiny touch of solder for a reliable connection of new pins to the wires, if you can't borrow a tool.
