Default How to wire a 05 MSM TB to a 90 Wiring harness

Hello, as the tittle says, I am trying to figure out how to hook up a 05 MSM TB to a 90 Harness, or to just hardwire the TPS and IAC*? to the Megasquirt.

MS 1 V 3

Also a good place to buy the pig tails for the two new sensors on the TB.

both the Throttle Body and Idle Control valve connectors/kits/pigtails on this page are for NBs. I used the 'kit' and crimped my own terminals using this tool - Home Shop Tools Crimp & Strip Standard Crimper for Weather-Pack ( Weatherpack ) and Metri-Pack ( Metripack ) 150, 280, 480 and 630 for 24-14AWG

As for actual wiring - the IAC sensor it doesn't matter which wire goes where.

For TPS wiring I don't remember but its not complicated. This looks right.
