IVA, IVA!

2 things have been causing me grief. The first one is immobilisation, the second, headrests.

The IVA manual was updated on 29/06/2009. The requirement for an electronic immobiliser installation to be certified has been dropped. This is great news as I was going to fit a new steering column incorporating a working ignition switch and steering lock. It would have meant cutting a big hole in the dash and altering the wiring.

I have been looking at the Cobra 8510 Cat 2 immobiliser. It is a touch-key dual-circuit unit. I can install it on the front bulkhead isolating the fuel pump and starter. All for £30.

Next issue, headrests. One has to be careful when fitting headrests, the IVA manual has very specific requirements. The headrest size must be 85 mm wide each side of the vertical centre line of the seat and at least 100mm high. So what happens if your headrest is round like mine? The top of the headrest must be no less than 753mm above the seat squab and there must be no more than a 50mm gap between the top of the seat back and the bottom of the headrest. I have a set of the Sylva / Intatrim seats. Next time I'm the workshop I'll measure them up and let you know!
