I went to Auto Zone today to buy a relay ... jeeze! They have so many different versions, I had to just bow out and leave.

Is there a particular car/year/model to ask for that will get me the relay (male & female) I want?



Where do you guys buy yours?

I completely rewired my 240Z from scratch (to accept the LT1/T56). None of the OEM wiring remains. I got my fuse block, relays, connectors etc from www.waytekwire.com. great prices, excellent service and just about anything you could possible want.
Their website is kinda confusing to order from, so I would recommend getting a paper catalogue.

Thanks, Tim

I'm hoping to buy locally, so I don't have to wait a week ... maybe the part numbers (from your site link above) will get me there.

PS -- Check out THIS place ... prices are less than half of Waytek's:

Radio Shack sells a 30 amp automotive relay under part number 275-226.

Go into to any automotive parts store with a relay part number and have them cross reference to whatever brand they carry.

A Bosch 40 amp relay is part number 0 332 019 150 (SPST) with mount bracket and 0 332 019 151 (SPST) without mount bracket.

Hmmm ... I went to Radio Shack today and their stock was crappo; nothing I wanted in a relay.

Then I called Pep Boys and they couldn't cross reference my Bosch part number -- they could only find a part according to year, make and model (can you believe it?) -- what a pain in the neck!

I'll try Auto Zone tomorrow -- the Bosch relays I've been using are #0-332-209-150 ... also the relays I saw today at Auto Zone were like $15 each and the link I posted above hooks me up for $2; worth waiting for, eh?

Thanks for your post 32Vicky.

The Bosch part number you listed is a SPDT 40 amp relay. This gives you the NC set of contacts in addition to the NO contacts. If you aren't using the NC contacts, the part numbers I listed will do the same job.

I have also been looking at relay availability and pricing. I've come the the conclusion that I'll be ordering mine versus picking them up locally. I hate to not support the local boys, but they want 4 to 5 times the price of mail order.

[horvath]

I agree. I wanted to buy locally, mostly because I'm impatient ... but when I can buy a half dozen relays (male and female) for the price of ONE (male only), I'm happy to wait!

PS - What are the "NC set of contacts"???

NC is normally closed. So with no power applied to the relay coil, the NC contacts will be live. It is the post in the center labeled 87A.

Ahhh ... I've wondered about that bugger. I haven't used it in any applications so far; headlights, electric radiator fan, AC/Heat blower, backup lights, and now my dome light.

I've learned a lot about relays this month - pretty cool additions to my truck's electrical system!

Do you have a truck supply store nearby? They sell a relay kit for truck lighting that I've seen used on a lot of cars and is a quality part.

go to the junk yard and on most 80 chevys there are a couple relays by the right front headlight.cut the wires and take the relay and cut lead, and from there it should have a digram on the side of it and you can splice it in.

cheap and quick and in my younger days the junk yard was open all night and it was free.

[horvath]

Thanks, again ... no truck supply stores around here, but I'll remember that one.

And, oh, for the days when junk yards were free and open 24/7!!

PS - I ordered a half dozen Bosch relays from Parts Express (see link above) ... they only carry the SPDT relay and it's $1.99; the female component is $1.50, so the whole relay is $3.49. Not bad, eh?

You can order them here: 1-800-338-0531
Male Part #330-070
Female Part #330-075
