Lextreme EGR Delete Kit Install on 1992 SC400

[Lextreme]

A customer is saying they're getting a CEL because "the resistor won't work for this style EGR system. The way I understand it is that the older systems were operated off of vacuum, not electronically."

Can anyone help?

I have the same question. Trying to delete the EGR on a first-gen LS400 and am confused because there's no temp sensor since the valve is vacuum-controlled. If I delete the EGR won't it trigger a code 71? There is a gas temperature sensor in the housing that detects exhaust gas heat. No heat, no egr function = code 71.

Help?
