That sounds like insurance fraud, be careful my friend works for a insurance company and they even track people down on internet forums to come up with excuses not to pay people. Most insurance company’s will do anything to not pay you, it doesn’t take much to look at your wire loom to see if its been modified and cut into. I remember one claim my friend told me about with a s15. A boost controller had be fitted and the person crashed their car and then removed the boost controller. The insurance company inspected the wiring concluded a boost controller had been retro fitted and refused to pay the claim due to undeclared modifications, so just be careful.
