Defender Heater Blower 300tdi to Puma help.

[Stazzy]

Hello to everyone.

I recently had to replace bulkhead in a Defender. And had to upgrade from 300tdi to Puma type.

This means I have to put new style dash.

But bulkhead and dash have all duting for new type of heater blower.but also I am worried about controls.

Could anyone give me some advise. Should i bodge it and try to somehow fit old heater blower or upgrade to new style.

But if I do latter, how would it behave in terms space in 300tdi engine bay and what electrical connections would i need, Would I need an ECU?

Thank you for help.
