Underhood Electrical Connectors '91 745 T Wagon 700 1991

Evening everyone, and Happy New Year! Question: I have been trying to find a decent source for buying the Electrical Connections under my hood. The ones I havce are completely falling apart (the plastic/rubber inserts in the connectors that the wires pass through). Is there a decent place that is not outrageous in price?? Please help! :)

    Wow, you are either really brave or really desperate.

    Many modern cars use signals that are less than 1 volt. Adding a lot of new connections to your car could take you to the wonderland of defective auto electrics.

    I suggest that you repair the connectors that really need repair, but do not get into improving things that still work.

    I would only repair one connector each week and drive the car several days to see if the repair is really adequate, That way, if your car acts up, you know where to look.

    When my '90 745 TI started to act up when I was trying to sell it, I found that the issues were electrical. I hate to let a car sit - I think that road vibrations help to keep connections better.

    I was told to clean every connection, apply dielectric grease, and zip tie any connector that I could. I did one each week (as I recommend) and got rid of my gremlins (my TI was not an airplane but at times it flew).

    Don't forget to clean/repair all of your grounds!

    While each connection is apart, look inside each connector to make sure none of the pins have not been pushed back out of place. Since that same thing happened to the AMM on one of our 740s, I always look for that issue.

    A friend of mine uses Nissan connectors for his hot rods.

      wasn't looking at replacing the "connectors", just the rubber boot on the connectors. I did, today, have to get two replacement connectors (boot on them, from volvo shop)... will require a splice, solder, shrink wrap, etc. But, since BOTH connectors broke off as I was reconnecting after head work, find it necessary. part number for the new connector end (female) is 3523813.

    You're talking about cutting the connector end and replacing? Volvo sells the pigtails that can be butt spliced to the old wires as well as new plastic connections for a resonable ammount.

    If I can find an old order I'll post the numbers.

    Dave Barton has some good info at http://www.davebarton.com/volvoharnesses.html#FAQ_5 .

      Yes, indeed, I am talking about cutting the connector and replacing it either with a used connector in excellent condition or acquiring a new connector and soldering it in.... I never use butt connectors, as they are absolutely unreliable, and are easily replaced with a few minutes, some rosin core solder, and an a pair of able hands wielding an iron.

    I'd love to know too! I believe some people have installed the connectors, then filled in the back of the connector with liquid silicone. I hear that once it sets up, it makes a pretty decent replacement.

    Still, I'd like to get some new connectors.

    Good Luck!
