Connector for K-Series throttle position sensor?

[Roger Ford]

Anyone know the type (and preferably source) for the throttle position sensor connector on a K-Series?

Mine's been bodged with three 2.8mm spade connectors.  Would be nice to get the proper connector on it.

Ta.

Polevolt. I think it's the 3 way junior power connector, but without going into the garage I'm not 100% sure.

You'll also need to buy the terminals, wire seals and boot at the bottom of the page.

[Roger Ford]

Thanks, that looks right.

Hi Roger,

I recently got one of these from   angliapostalparts.co.uk  (sorry don't know how to do linky thing!)

Three pin Junior Power Connector and tails, Part No.  E68.  Comes complete with 12" tails all assembled with the seals and rubber boot ready for splicing into the loom.

Got it from them via E-bay, About a fiver or so delivered from memory!

If you buy the plug and terminals, you don't need to do any splicing. But you need a proper crimping tool for the terminals. 

[Roger Ford]

The wires are damaged and have been bodged, so I'll need to do some splicing anyway. I'll take a look on eBay.

[Roger Ford]

The ebay ones only have 150mm wires on them. I think I need them to be rather longer than that, so it looks like Polevolt.  That way I can buy the correct colour wires to match the existing ones in the loom. Don't fancy paying 43 quid for a specialist crimp tool though, so will have to rely on careful crimping with pliers. Works OK with Econoseal, so reckon it should be OK.

[TomB]

No, get a proper tool. Polevolt do a budget one for about a fiver. It's ok for the occasional job like this - I bought it last month!

The TT310 from Polevolt (£22.50) works well with Econoseals so I can't see why it wouldn't cater for JPTs.  Better than pliers which IMHO are not a good idea as they can't produce the "B"-section crimp.

These are what are bought http://www.polevolt.co.uk/acatalog/info_TT70.html

[Tony Whitley]

I'd buy a ratchet crimping tool for £12.49 from Screwfix as I've never had much success with the scissor type.

[Richard Price]

Tony,

No. That tool is designed to crimp closed industrial uninsulated lugs, rather than the crimps that are an open "U" that is folded inwards.

Roger, other than the TT70 from Polevolt referred to by Tom, all the other links are to tools not suitable for the job you're doing. However rather than the budget tool Tom's linked to, get the more mid-range one from Car Builder Solutions: http://www.carbuildersolutions.com/uk/proper-f-crimp-crimping-tool

I'll guarantee you've spent more on other tools that are less important.

[Roger Ford]

Thanks Stu. That looks to be identical to the one sold by Vehicle Wiring Products for quite a lot less. I guess it could be a cheaper copy, but as VWP have everything else I need I'll take a gamble on that.

[Roger Ford]

OK, that's done. The crimp tool didn't do a brilliant job, the JPT connectors are slightly smaller than the middle position on it. I ended up crimping the insulation part by hand, then using the tool on the wire part and finishing it with my trusty long-nose pliers.

Now while I was doing that I noticed that the wires leading to the coolant temp sensor were cracking up. Cursing myself for not having noticed before I sent another order in to Vehicle Wiring Products for a 2-way Junior Timer connector and associated hardware and wires.

Made up the connector, soldered up the wires - and found the connector didn't fit.

See pic below:

On the left we have the original connector.  On the right is a 2-way Junior Timer connector. Note the cutout at the top is offset to the right on the original, but in the centre of the JT connector.

I went for Junior Timer rather than Junior Power Timer based on the rear view - no built-in seals with the JT connector, but a fitting for a "boot" instead.  But I'm told they're compatible anyway, and pics of the JPT connector show the cutout in the centre as well.

So anyone know what this special version used by Caterham is? I can probably bodge it with a couple of 2.8mm female spade terminals if necessary, but I'd rather have the right thing.

It's Rover YPC114920 which is actually available as BMW Part No 12-52-1-427-787 Code III (the coding gives you the correct offset for the keys).Terminals are SLK 2.8 ELA, not Junior Timer or JPT.

[revilla]

These are the correct crimp terminals to fit the above housing:https://www.ecstuning.com/b-genuine-mini-parts/socket-terminal-slk-28-ela/12521427612~oem/

Here you go: http://www.ebay.co.uk/itm/291458243100 Sorry can't do proper links from my phone and I'm away from home at the moment.

[Roger Ford]

Excellent, thanks. Not clear from the ebay ad if it comes with the terminals - let's hope so.
 

[revilla]

Suspect not, that BMW part number is a bare housing but the terminals are fairly widely available if you search for "SLA 2.8 ELA". If you're really stuck I'm likely to be ordering from somewhere that sells them soon and I can add a couple to the order.

[Roger Ford]

Shipping for 2 x $1 terminals from the US is $48.62!

[revilla]

Wow! Well I shall be ordering a pile of bits for various loom bits I'm involved with so I can just add a couple on for pennies if you want?

[Roger Ford]

Same vendor has this which I think is correct, but he's only listing one of them. Whether he realy has only one, or doesn't know how to list multiple items (there was only one of the housings listed as well), I don't know.  I've asked.  Can't find it anywhere else in the UK, unfortunately (I presume it's SLK rather than SLA?)

[Roger Ford]

Sorry, missed your previous post. Yes please!

[revilla]

Less than 30p here (from Finland so not worth ordering on their own but will not add any postage to my order).
