1. Disconnect the rear portion of the chassis harness at the battery, oil temp sender wire, fuel pump, engine bay light, 14-pin connector at power panel, ground point under power panel, both taillights and both license plate lights. Loosen tabs at rear firewall to free up harness and pull harness through engine shelf hole to below the engine shelf.
2. Remove the plastic connector housings at the 14 pin, fuel pump and oil temp sender wire, record the wire position by color/stripe at the 14-pin connector.
3. Cut off the old snorkel grommet. Slide on the new snorkel grommet (be sure the correct end goes on first) using plenty of KY jelly as lube - nothing oil based. Clean off the KY residue after installation. Its a tight fit and patience is required to be sure, but the KY is the secret sauce.
4. Reconnect the harness to everything.
If you have a good, crack free snorkel you get it off by doing somewhat of a reverse order.
I didn't believe that you could do it, but the young lad and I managed to get his off perfectly. No way could you do that on mine as it has spider cracks all through it.
Removing the big connectors is the only way to do this or remove the whole harness from the car. You have to make an order drawing, but it's totally do-able without damaging any wires.
