Efi Computer Plug With O Ring

If you still aren’t sure what you are dealing with, a rule of thumb I’ve been using for years is this: If the plugs that plug into the computer have O-rings or seals (arrows), then it is safe to put it under the hood. If the plugs have no seals, it needs to go inside the Jeep behind the dash as I mentioned earlier. Another thing to mention is that aftermarket fuel-injection computers from those years follow the same basic ideas as what I was talking about, both above and with the O-ring plug thing. I just mention it in case you score a used aftermarket setup and get to wondering.
