Posted this question in the Cosworth section but thinking the tech section might be more appropriate and get a response.

Would appreciate some advice with the fitting of the Sierra ABS master cylinder and pump into my Cosworth powered Capri. I’m just after doing the conversion that uses the main pump without the separate ABS valve block but I’m struggling with the plumbing in of the brake pipes to the master cylinder itself (see pic).

Could anyone who has done this conversion please let me know which pipe goes to the front brakes and which to the rear? I understand that the fronts need to be split and that perhaps the middle outlet needs to be blanked off, is that correct?

Or, am I better finding a separate valve block and just plumbing it in as original without the ABS working?

At my wits end with this so any help will be really appreciated. Cheers.
