I dont know why i would go poking around C100 and C101 without touching them before.. everything should...

    small MTX swap milestone

    yea?! even though I didnt touch those? I never touched either end of the 101 or 100.. The only one that connects the engine harness to the body harness is c104 (grey 16 pin) above the bell housing in the center of the trans. Havent gotten to far into it but looks like I'll have to dive in soon

    Frustrated with MTX swap

    I am going to use the Engine, trans, Engine harness, CCRM, And PCM from a 95MTX in a 93 ATX... so The rrcm and pcm will be looking for a high pressure cut off switch.. so I can use the 92/93MTX lines and accumulator if i just jump the high pressure switch. Or I can use the 95MTX style lines...

    Need some ATX-MTX swap question answered

    Everything is set back an inch and change... The MTX subframe only mounts with the MTX accossories, only with the MTX timing componants... You can make your ATX stuff work, but it does all need to set bakc the same distance because of axle shaft lengh and angle from the MTX trans
