All About Relays: Identification, Uses & Prices

[infotechplus]

I thought I would start this thread as there didn't seem to be much currently available that was easy to access. I know from inputting part numbers into GOOGLE that some come up and some don't. Those that do are really 'hit and miss'. So this thread is a consolidation of everything that I have found - it's not exhaustive but hopefully it will serve as a guide to anyone else trying to find, identify and price a Toyota Relay.

Over the last few weeks I've been working on the wiring for the Hilux 1GGZE conversion and in doing so I've conducted numerous sorties to Pick 'n' Payless (Blacktown) looking for wiring, plugs & sockets, and, of course, relays.

Here are all the relays I've grabbed from the wreckers, plus information from researching 'round the Web, and talking to Toyota. It has taught me a lot about auto electronics and reading wiring diagrams. It may be taking a while to do this wiring but along the way I'm learning quite a lot, and to me, that's a real benefit in the future.

The other thing that amazed me was just how much these relays cost when you have to go to Toyota's Spare Parts Department for them!

Toyota Relays

Circuit Open Relay
Part No.85910-30050
NipponDenso 061000-0350
Cost (RRP + GST): $136.35
Note: The Toyota Circuit Open Relay has dual windings and is mounted on the firewall. One of the windings is connected between the starter relay points and ground. The second winding is connected from the battery positive terminal to the PCM when the engine is cranking and the starter relay points are closed, current flows through the starter relay points and the circuit opening relay to ground.

This current flow creates a magnetic field around the circuit opening relay winding that closes the relay points when the points close, current flows through them to the fuel pump when the engine starts, the starter relay is no longer energised and current flow stops through the relay points and the winding of the circuit opening relay the PCM grounds the other winding of the circuit opening relay ~ this keeps the relay points closed while the engine is running.

The EFI main relay serves as a source of battery power for several components including the Circuit Opening Relay, (which powers the fuel pump), the fuel pressure up VSV and the ECU.

Nice work. Any idea what relay Toyota generally use for thermo fans? +rep

All About Relays, Part 2

I've tracked down a few more relays and some senders. These ones are what I call the "pin" type, for want of a better description.

PIN RELAYS



Relay M3
Part No.90987-01003
NipponDenso 056700-4800
Cost (RRP + GST): $46.20

TOYOTA SENDERS



Fuel Injection Sender
Part No.89422-20100
Cost (RRP +GST): $69.30

MA61TURBO - To answer your question: The parts guy said this water temp sender would control a fan but couldn't give me any more details from his catalog eg. it's operating range. Maybe someone else can shed some light on it. I actually pulled it for that very same purpose. He suggested an auto electrician.

Water Temperatute Sender
Part No.89422-30020
Superseded by Part No.89422-12010
Cost (RRP +GST): $80.30

Water Temperature Gauge Sender (?)
Part No.
Cost:

Sorry, not much info on that last one as there are no identifiable markings except as noted in the pic. Maybe someone can provide an answer.

Great info, +rep!

Good resource, +rep.

Any reason, since your wiring up your stuff from scratch almost, not use relays that can be had from jaycar at a much more realistic price?

On a side note:
Your 4 pinned relays are single pole single throw (SPST) meaning a singnal either turns them on or off therefore either making or breaking a circuit.
Your 5 pinned relays are Single pole double throw (SPDT) meaning while connected to power on the switch side they always flow current but when applied power (or trigger current) to the pole side they switch the power to another circuit. Ie 1 of 2 things is always on but the relay switching decides which one.

Also i recently bought some relays 12v 30A fused SPST relays and they were $12 from jaycar iirc. Supercheap also sold the relay holders for them which where around $5 and came with all pins to connect wires into them.

I dare say that the jarcar relays should clip into the toyota relay holders and also provide a cheaper option.

Either way, awesome work and some good info. I can see this helping people id relays at a wrecker and saving a good few $$$ in comparison to the toyota (expensive) option.

Edit: will rep after i spread man love more

I dare say that the jaycar relays should clip into the toyota relay holders and also provide a cheaper option.

What I didn't say was that I got all these relays (including multiple units) from Pick 'n' Payless for less than $40 all up, including $25 for a complete junction box that had the Fuel Pump Relay on it.

The point I was trying to make was that to buy from Toyota the same genuine part would cost you an arm and a leg. Far better to hunt around the wreckers and see what is available - in most cases it is possible to find everything you want.

I also asked Toyota the price of a Fuel Pump Relay for a LandCruiser as there was one on Ebay claiming to be over $500 new. The relay was $530.00 inc. GST. A quick search at the wreckers turned one up

I could have gone to Jaycar; in fact, I downloaded a whole swag of BOSCH Product sheets which I then took to REPCO to price. Some items were mid $20 but because they had to be ordered from BOSCH, Repco wanted a delivery fee which pushed the price up over $30. Plus, I wanted to keep my wiring as genuine as possible - nothing is going to do the job better in a Toyota than a genuine Toyota part

Either way, awesome work and some good info. I can see this helping people ID relays at a wrecker and saving a good few $$$ in comparison to the Toyota (expensive) option..

Absolutely! That was the purpose of this thread. Identify what you need and save a heap of $$$$.

I promise you the rep is comming after some love spreading. That hilux thread is worth 2 reppings methinks

Keep up the good work

fused relays for $12!

ive been patin bout $15 at Supercrap for 5/4pin 30amp relays! DARN IT!

frign supercrap


as always infotech ... quality work .. need to catch up when our rides are done ... quite interested in you classy works.

[sideshow]

12 bucks fuk that
i bought 100 bosch relays

never have any problems with them
can sell them for less than what supercheap do

supercheap are weird alot of stuff is cheap but it is so fukin crap

then they have other cheap looking stuff and its expensive

i ony use bosch relays and sometimes i might use narva

or i will use 2nd hand nissan and toyota relays cannot beat genuine ones
aslong as they havnt been soaked with water when the engine gets degreased when coming from japan

Stuff buying the aircon relays just go through old toyotas at the rweckers and get a handful of them for 10 bucks lol. Just don't get them out of coronas cos they blow them.

MX73 cressidas, and AE82 rollas have them under the bonnet so they are in good nick. Stupid ronas have them in the passenger footwell.
