RHD Conversion

<< < (4/4)

Sassy:
Hey troops, just wondering if anyone has used a Saginaw style power steering pump with the XF RHD conversion into a 65 V8 coupe. Thinking of using a mid 90s Holden V8 pump, any ideas?

Edz:
Much easier and neater to fit a Holden Barina/Astra pump under the front mudguard and just run 2 hoses. They do pull 15 to 70amps but neat and clean.

This is one under the front left mudguard on a Mustang.


This is the wiring for an Astra Power Steering Pump that I put together.



The pumps draw approximately 15A when idling, and between 15-35A when steering, up to 75A at full steering lock and when driving aggressively like drifting.

Outlet – M16 x 1.5 to AN6 fitting for high pressure side

Pump Wires
•   Thick Brown – Earth
•   Thick Red – Power (70A or 100A recommended - Jaycar breaker $50 or $15 on eBay)
•   Thin Black – Ignition on
•   Thin Blue / White stripe – ignition – 2 second delay brings pump straight to speed. If you connect this directly to ignition, the pump will take 10-15 seconds to get to full speed
•   Brown/white – if present - diagnostics OEM, not used

Cable to buy
Black earth cable 6 AWG 13.5mm2
Red Power cable 6 AWG 13.5mm2
8/10 mm Ring Terminals for the battery

2 second Timer Delay Relay
If you power the thin Blue/white wire 1 or 2 seconds after the thin black wire, the pump will start quicker, otherwise it can take 15 seconds to get to full speed.

You could use a $130 Narva Multitimer Relay (P/No 68076) 12A 10A to give a 2 second delay (cheaper ones on ebay)

Wiring: Pin 30 - 12V constant; Pin 31 Earth; Pin 15 Ignition on & Pin 87 – 2 second delayed ignition on output to little Blue/white stripe

Cheaper option; $2-$6 on eBay - DC 12V Signal Trigger Relay delay time Turn Off on Timer Control Switch Module 2-10 sec (Plus $4 Jiffy case at Jaycar)
 


 

Edz:
This is a Youtube video that explains it.

Sassy:
Thanks Edz for the info, sorry for late reply. I had heard of the Astra setup but was not convinced,will now look into it further.       

Edz:
No worries, if you have efi, you want a delay on the pump or it drops the voltage on startup and the efi may not kick in.
