Best entry point for new cable from engine bay to dashboard

[blaze_away]

I am in the process of installing a wideband lambda and the sensor is in the exhaust Y piece and the gaage needs to be in the dashboard.

This requires running the connector and wires between the gauge and sensor through the bulkhead. Needs to be about a 25mm hole, so what would be a good solution, use an existing hole or drill a new one if new then where abouts ?

Via the bonnet release cable opening or my preferred choice would to feed it through the big grommet the ecu wires go through into engine bay.

Remove the clutch reservoir cover. You can access the drivers footwell from there using a long stick

Yeah, if you're going from the y piece you could go from the front of the radiator and run it all inside the wing and out from the pedal box, long run though and you'd need a big poking stick

When the PO of my old Chim' decided to do away with the heating and some of the venting he made a hole in the dash where the RH vent was to mount the gauge. The wiring was in place but I have no idea where it was routed. Nedless to say he had some offbeat ideas.

Thanks all, I will explore all those suggestions, though probably not lancespars PO (wtf was he thinking ?)

I have a good length of cable to work with so any of those might work, but its got a big nobbly connector one end and a ecu box the other both hard wired so one of then has to go through the bulk head. smallest is the connector needing 1 inch hole to pass through.

Any chance of a pic or two?

Easier to just drill a new hole, I did when replacing the battery cable.
Mine was just above the battery level in the side of the transmission tunnel but almost next to the radio if you like.
Think from memory it was next to where the heater hoses enter the car.

I haven’t tried this but came across it on the internet recently.
Bluetooth solution ... need to find a place for the control unit but potentially no holes needed.

Put mine in the inner wing and fished the lead up the void ends up in the passenger foot well

Heres the kit


This is the plug that has to through the bulkhead


Looked at various options suggested and ended up cutting a new hole under the MAF and used electricians cable pullers all sorted.


Just need a grommet now.

Thanks for your help folks.

PS Test run at idle and all running good with about 14.7 to 1 at steady idle

Bit late now but just past the removable panel under the AMM earlier cars have fitted

[Penelope Stopit]

Damn, blast, too late, hole is already cut

Could have removed the terminals from the plug

No problem though, car might be a touch lighter

Oooohhh b&gger, I will post pics early next time.

Looks like 35 mm grommets are rocking horse dung so will glass it and add sealant

[Penelope Stopit]

Mmmm

Am feeling a touch bad about this now

Should have asked you if there was a possibility of removing terminals from any of the plugs instead of asking for pictures

I apologise

Original Mini but last of with EFI have large oval bung for fuel pipes may be worth a gander , don't know dimensions though https://www.minispares.net/product/grommets/wya100...
