No clue what that’s gonna cost, but I wager it’s spendy. On the intense aspect they showed me where the change was and the way to manually enable/disable 4wd by splicing the vacuum lines together with a snippet of brake line Performs similar to a attraction in Hello and lo now making sure that seemingly procedures out the remainder of the process.

The battery cables are pretty limited, so I eradicated the battery totally to operate about the technique, then set it back again in on it’s aspect to check it (but don’t go away it such as this for prolonged — it will leak!).
