Dual injector TB - cable difference

stiglarsenDK

Found these 2 NOS TB for 996 and plan to use them for ST4S engines w P8 box/996 SPS chip. The female connectors are missing 2 pins Marked A and D ref Foto. The first build with same configuration is using a SP5 TB harness having all connectors there.

What am I missing here, should I rewire the 996 TB cables to match the SP 5 TB cable or will it still work as planned.. any diagram available on this circuitry? Thanks

the p8 dual injector throttle bodies control all injectors individually, so 4 injector trigger wires are required into the throttle bodies.

the 1.6m runs them as two pairs, so only 2 wires into the throttle bodies, that then each go out to both injectors on a given cylinder.

if you want to run a p8 dual injector eprom you need all the wires in the throttle cable connector.

Thanks mate.. I'll modify the cables/ female connector on the new TB from 996 to mimic the SP5 /996 sps 2000 cables , much apriciated
