NC 3.5 screenwash bottle removal - how to disconnect electrics

  1. My model of MX-5 is: __ NC 3.5 2.0l PRHT
  2. I’m based near: __ Manchester
  3. I’m looking for technical help or recommendations on: __ Removing the screenwash bottle

So, I’ve undone the two bolts holding my screenwash bottle in place (proud of myself for that), and disconnected the couple of mechanical “clips to other bits”.

Managed to lift the screenwash bottle up and out a bit (applause, please!). I can see there’s an outlet hose for the screenwash (I’ll leave that till last!!!). But I’ve also got the electrical / pump connection. See enclosed photo

What I can’t work out is: How to release or undo that? Does the whole black electrical assembly pull out from the bottom? Or does the top bit of the black electrical assembly come away from the bottom of the black electrical assembly? I can see there’s a tiny black tab just beneath where the wires come in - Do I push that tab in, then pull upwards, or what?

Don’t want to be a numpty and apply too much force in the wrong place or direction, so call guidance gratefully received folks. Thank you.

Use a little flat screwdriver to push the ribbed tab down, then pull/wiggle the connector upwards and it will disconnect:

You’re left with the pump in place, with an L-shaped electrical connector on it:

Thank you Steve! Electrical / pump connection now released successfully :grin:

Two small additional tips from me, having just done that.

  1. A squidge of WD40 onto the connector, and letting is soak in for a couple of mins, seems to help the two “halves” of the black electrical connector come apart more easily

  2. The hose / tube for the screenwash fluid might sit quite tightly on the bottom of the screenwash reservoir. I think aiming a hairdryer at it for a couple of mins to warm and soften the rubber a bit may help it come off more easily

Good stuff, glad you’re sorted and those extra tips sound good/sensible to me :+1:

Good for releasing, but clean it off the contacts if you want a reliable electrical connection on re-assembly.

As well as a Water Dispersant, classic WD40 is also an excellent electrical insulator.
