I believe you are correct, so rather than towing you would be towed!

QuoteYou can still use them. Pop out the cover, unplug the sensor & screw in the towing eye

Bravo!

I guess you are no different to other Members and seldom have need of the rear tow eyes.

Check ECP though, sometimes they have good prices on them.
Bear in mind the sensors are all the same, you just need 4-wire, thread fitting, Toyota plug & a long enough cable.
I've found a fe 'bargains' on ebay over the years.

Due to car accident 39 years ago I do not have full neck movement and so find parking aids very handy, plus my daily, my wife's & both my kids cars have them and so when reversing these days I tend to forget the MR2 doesn't have them   

I've been wondering how I could install a set but so they are very subtle. Yesterday I had an idea and I have installed mine. They are Steelmate sensors and you can either fit all 4 or 2 sensors. On the pre face lift there are towing eye covers each side and I mounted a sensor in each one. Cables are in a conduit similar to the grey used on main engine loom & run through the bumper crash beam. I extended the sensor wires using the now unused other sensor leads using solder and heat shrink & mounted ecu under plastic trim in cubby hole next to fuel sender.

Works a treat, not quite as sensitive as when all 4 sensors fitted but they work well & are virtually invisible.

Check for leaks at the manifold to cat joint.

Is it a proper type approved cat or a 200 cel 'sports cat'?

The post cat sensor will have been subjected to a bit of a hammering removing it from the old cat and these sensors are quite delicate, but I would check for leaks before spending the money.

The other two sensors should be fine.
