Review on Labwork Evaporative Emissions Replacement Chevrolet by James Small

If you are unable to make a plug and play connection because the large wire tubing is the only access to the connector, you may need to cut the old one and reconnect the wiring to the new connector if you think that it is defective (along with canister and filter). Before you even think about it, try plugging the old plug into the canister, then clear your codes first. If that doesn't fix the problem, try rewriting it. BUT, if you must do this, be aware that you will need to purchase an OEM factory wiring harness to rewire, as the wiring harness sold here is made of silver aluminum WHICH CANNOT be mated to COPPER.
