No other harness is compatible. It HAS to be the one made specifically for the 1st gen LS. It seems that all 1st gen LS's use the same one.

Since many Toyotas and Lexuses use the same knock sensors, I am thinking that maybe we could improvise these wires from some other harness that is most similar to it? Ours (1st gen) has four contacts: two for knock sensors, one to the starter (which should also be the same on many other cars, right?) and one to the engine harness - plugs into it right at the firewall.

What do you guys think? Should we contact some independent shop that makes wires by order and make a group order? I mean, it is just a well insulated piece of wire with four contacts after all... how hard can it be to make one?

If we do not come up with a solution, we are destined to junk our cars the first time they develop knock sensor wire problems, and I would hate to do that.
